Improving the current invocations

[metaquad4]

Right now, warlock invocation choices are, for the most part, no-brainers. There aren't many real useful ones. So, I suggest we improve the current ones to make the choice between warlock invocations at-least somewhat challenging:

Hideous Blow:
Make this renew every new round, and every 2 attacks. What this will mean, is that the first attack of a round will have a blast attached to it. Then the third attack in a round will have a blast attached to it. Then the fifth attack in a round will have a blast attached to it. Then, the process will begin again in the following round. In addition, make it give +2 AB. The warlock will get a small boost in AB to help with hitting, and can potentially get 3 blasts in a round, to compensate for the fact that they have to hit with an actual melee attack. Warlocks could go fighter, as they have in the past, but dispels and SR will make this route more painful.

To recap, the attacks in a round would go like this:
1st Attack (Blast), 2nd Attack (No Blast), 3rd Attack (Blast), 4th Attack (No Blast), 5th Attack (Blast), 6th Attack (No Blast), 7th Attack (Blast). If all 7 attacks are available and they all hit, the warlock can get off 4 blasts/round, due to haste's attack.

Frightful Blast
Remove the HD requirement, and make this a fear effect (lasts 1 round/warlock caster level) upon a failed will save.

Beguiling Influence
Make this +CHA mod to Bluff, Diplomacy, and Intimidate for 1 minute/warlock caster level + 1 minute/CHA mod.

Devil's Sight
Make this +CHA mod to Spot and Search, as well as Dark Vision for 1 minute/warlock caster level + 1 minute/CHA mod.

See the Unseen
Make this Dark Vision, See Invisibility, and Detect Spirits for 1 minute/warlock caster level + 1 minute/CHA mod.

Otherworldly Whispers
Make this +CHA mod to Lore (All), Craft (All), Sense Motive, and Spellcraft for 1 minute/warlock caster level + 1 minute/CHA mod.

Charm
At CL 21 Warlock, make this a dominate effect.

Curse of Despair
Make this a large AoE, and make it apply 6 damage to ability scores on a failed save.

Dread Seizure
Make this a large AoE, and make it still apply the movement speed loss on a successful save.

The Dead Walk
Make this summon up to 2 undead at warlock CL 10 and up to 3 undead at warlock CL 22. (As with animate dead, with a lower maximum.)

Voracious Dispelling
Make this the equivalent of a greater dispel, like Devour Magic. Make its damage uncapped and make it CL*1.5 + CHA mod.

Brimstone Blast
Make it continue even if a reflex save is made, further reflex saves being rolled until it is done. Increase its DoT damage to 4d6.

Eldritch Cone
Overhaul eldrich cone's functionality.

Eldrich Infuse:

The caster makes a melee touch attack against the target. If they succeed, then the target is effected by their eldrich blast, and anyone within a "medium" AoE must roll a reflex save or also be effected.

Hindering Blast
The least invocations already have a slowing blast. Overhaul this one:

Sonic Blast:
The damage type is changed to sonic, and the enemy must roll a fortitude save or become deafened for 2 rounds.

Tenacious Plague
Change to act as creeping doom does, but with 3x CHA instead of 2x WIS as the determiner of its AB.

Devour Magic
Make this heal for 2*Caster Level and grant Caster Level+CHA mod in temporary hit points upon successfully dispelling magic.

Eldritch Doom
Change to be a "large" AoE instead of a "medium" one.

Utterdark Blast
Make this spell targettable on allies (to heal undead minions). Make the negative levels stack.

Word of Changing
Change to Baleful Polymorph's functionality.

Hellspawned Grace
Merge Word of Changing's old functionality into it and add new forms, appropriate for multiple types of pacts.

Undead Baneful Blast
Make it deal 50% more damage against undead (instead of adding 2d6 extra damage) and make it apply consecrate's effect for 2 rounds to the nearby area.

Frightful Presence
Make it a "medium" AoE aura, which causes any enemies to go near you to take -2 to saves and -2 AB. A failed will save doubles these effects.

Instill Vulnerability
Make it an AoE, and make it cause 25% vulnerability if they succeed the save.

Caustic Web
Enemies who fail a fortitude save also take 2 STR damage per round while in the web.

Planar Ally
Introduce it as a 4th tier invocation.

[Azerkatil]

The only thing i disagree with in this build, is that people will then use Warlock with the hellspawn grace as the Ultimate loot farming Vessal.

[metaquad4]

A) That can be the current case, as with all polymorphs and with the current hellspawned grace. Carrying loot is a valid use of the spell (shapechange to carry a heavier object).
B) That is about all it is good for, and there will be other good invocations to take as well.

Also, packmules are a-coming!

[chad878262]

Just looking at Hideous Blow, that would be a serious increase in power. Currently a PTWF DSM/Rogue/SD/Lock has to pick between Hideous blow damage and sneak damage. Going this route, You would just go Wlck14/R3/DSM10/SD3 with PTWF you'd land 5 blasts per round w/ Eldritch Master for basically more damage than a full rogue would get out of stealth. You could frankly drop SD as you don't even need HiPS to land the dice, you'd just get them all the time. Could really just go Wlk16/DS10/BG4 and have 12 APR, 6 hideous blow dice per round. Too much.

Planar Ally
Introduce it as a 4th tier invocation.

Fear effect is massively overpowered, and DEFINITELY must have HD requirement. Otherwise you'll have level 10 warlocks mop floor with certain level 30 builds.

Existing bonus ability invocations should not add +cha bonus, because that will make them useless non non-charisma warlock.

See the Unseen: Definitely a no. Those are supposed to be 24 hours.

Dominate: Definitely a no.

Hideous Blow: Rather than trying to buff hidesous blow, attempt to introduce elditch glaive. Attempts to introduce eldritch glaive usually cause eldritch horror among other staff, though, because you can easily end up dealing 100d6*1.5 damage per round with it.

Hellspawned Grace: Definitely a no. There's a Shrouding Transformation invocation that allows warlocks to turn into creatures of their size, introduce that instead.

Planar Ally: Warlocks are not summoners. They can only draw forth swarms and raise undead. They can't summon anything on their own. Summon baatezu is a homebrewed junk by obsidian.

To summarize:
I would not want to see good portion that on on the server. Some of the suggestions have massive balance issues (like fear effect being guaranteed death), other gimp existing uses (replacing +6 with +CHA) and break existing strategies. Most of those have no good reason behind them and seem to be aimed at getting more mechanical power and without a good reason too.

• Painful Slumber of Ages: Greater, 6th, Mind-affecting; Cause one living creature at close range to enter an indefinite state of sleep if they fail the Will save. Normal stimuli is insufficient to wake them, but any damage received rouses them instantly, but they also take damage equal to your CL when this happens.

[Nemni]

I think many of these suggestions are quite overpowered. But I agree with the overall idea of adjusting the worst and least used invocations so that warlocks get more diversity.

Charm
At CL 21 Warlock, make this a dominate effect.

That is a good idea for example.

[metaquad4]

NegInfinity, I don't see any of those invocations in nwn2 or our server. If you want to suggest new invocations, there is already a post for that. Please stay on topic, thanks! Also, if you don't like homebrew stuff, stick to PnP (with a group that doesn't like creating anything new and can only use what is already created) and not a server hosted on a game based on PnP, which is also based on a game that was based on PnP.

Warlocks already have a stunning and a daze effect. Fear is in line with these two, even a little weaker (mobs running away can do harm if you draw more aggro from others).

Perhaps the stronger of +4/+6 (for the skill bonuses) or +CHA. Best of both worlds, there.

A name change for hellspawned grace can be arranged, but it doesn't seem worth the effort.

Giving warlocks planar ally isn't too OP, and it is rather fitting for their flavor. Especially with that many warlock levels, they are in deep with their chosen entity at that point.

Eldrich Glaive could be added, with a reflex save (PoS did this to some success). A max of two attacks, and a reflex save for half. But, that is a story for another thread!

Charm is pretty worthless (you can get damage+CC equal or better to charm with warlock blasts in an AoE). What other effect would be better, if dominate is too OP?

[NegInfinity]

Warlocks already have a stunning and a daze effect. Fear is in line with these two, even a little weaker (mobs running away can do harm if you draw more aggro from others).

Fear is incredibly overpowered when used against players. Pure rogue or pure fighter will have will save between 6 or 9, meaning a level one warlock will have a chance of scaring off a level 30 player. At which point idiotic neverwinter 2 fear system will kick in, and the player will start running around the map randomly, gathering mobs. If this is used in the right location, this can be easily used to fugue people via pvp (because a sneak will have bad AC, so getting them under effect of Fear will get them killed)

A similar problem exists with existing implementation of animal roar, which makes animals cast fear spell (DC vs Will Save) instead of using intimidate check (DC vs HD + Will Save modifiers vs fear), which results in ridiculous situation when a single CR5 wolf can send Level 30 fighter running away. This has been reported and hasn't been dealt with.

So, basically, by giving it a fear effect you're giving a powerful griefing tool at level 1. Original invocation had HD restriction exactly for this purpose. Also, frightful blast is usually something you use for the first 6 levels and then swap away. And not something you keep forever. Same thing applies to eldritch cone, by the way - usually by level 20 it'll be swapped with eldrtich doom, if the warlock is a high Charisma one. And that is fine.

Regarding Charm spell...
I checked the wiki, and it would seem the difference is that charmed enemy won't follow you.
I think that for its power level (lesser invocation) charm is fine as is, but you could consider introducing something similar to sigil's Baleful Geas:
http://sigil-nwn2.wikia.com/wiki/Baleful_Geas
Sigil also had a system where some spells had halved duration when used against players. So something like that could perhaps work.
Having a more powerful version at a higher level slot would be in line with progression of other charm/dominate effects (where dominate monster gets highest level spell)

in general, I think that proposed invocations are fine for their power level, but if you want a powerful version of them, it would work better as a higher level invocation instead which has limits removed instead of tweaking the existing invocations.

IIRC warlocks had relativley poor selection of either Greater or Dark Invocations, so if someone made a powerful version and placed it THERE, it would make sense.

Basically... the effects you're proposing seems to be too strong for invocation power level, and if you want to uncap them, they would make more sense as an invocation at higher power level instead.
----
Also, I do not recommend to use "there's already similar effect in other invocations, overhaul this one" kind of logic.

Most of the useful effects used by warlocks are centered in lesser and least invocations, and you can't pick all of them. In PnP version a warlock could swap away invocations for less powerful ones, so this was not a problem. However, in Nwn2 you can't trade a dark slot for a least slot, so this is actually an issue. So, if you, say, change a spell with an equivalent effect, you'll be probably breaking someone's build. Which is not a very good idea.

Bear in mind that, like the stun, the fear (should) would only last 1 round. There would be no "griefing potential" that isn't already there. Also, if players do that kind of thing intentionally, that is already covered by the rules. Really, a none issue.

And that is the danger of building an extremely low will save build. There are ways to compensate (items) or one could raise their willsaves with the right classes (or find ways to avoid such enemies or ambush them).

Cone should really never be used, and rarely is. Chain is way better, as enemies don't line up very well for a cone AoE.

Baleful Geas is an ok one as well.

Warlocks don't have a poor selection of greater or dark invocations. Rather, there are only a handful of really good ones. The least and lesser invocations are filled with less useful ones (with less must-haves than dark or greater). Dark has 3 extremely useful buffs (Dark Foresight, Dark Premonition, Ret. Invis) with one useful for cha-locks (binding blast), Greater has 3 very useful spells (repelling blast, vitrolic blast, devour magic) with one useful for CHA-locks (noxious blast), lesser has one really "must have-y invocation (eldrich chain), and least has 2 (see the unseen, leaps and bounds) as well as one for CHA (Dark One's Own Lock).

Player should decide what to use, and not someone else.

Chain and spear are for a dex-based blaster warlock. Cone and Doom are for Cha based contrller warlock. Cone useful for situations when you don't have eldritch doom. Also, at the levels when you get the cone, it works very well, because a lot of time will be spent crawling through dungeons. Dungeons tend to have door frames.

There is a loooot of power boost suggestions here for a class that is already very, very powerful.

Some of these are fine, but the large majority just come off as power creep (and some of them are very clearly PvP power ups, which makes me very wary).

[Argumantive]

I think the whole idea is to make the new or changed invocations powerful, to offer an alternative to the current ones.

A warlock has a -VERY- limited selection of spells. So any of these new invocations, will be replacing a powerful invocation as it is.

Giving more invocations, which will simply not be picked for not being competitive with the current ones, will be redundant and better not waste the time of even being implemented.

[wangxiuming]

I like most of the proposed changes/suggestions, although a few stand out as too powerful for me. Stacking Utterdark blasts, for example, is a frightening proposition even with a warlock's relatively low DCs. The Hideous Blow change is also rather terrifying - to potentially be able to deliver 4 eldritch blasts within a single round? That's potentially upwards of 4-500 damage per round with Eldritch Master.

Speaking of which...

Utterdark Blast
Make this spell targettable on allies (to heal undead minions). Make the negative levels stack.

This is a "kill anything" button, because it gives you infinite casts of enervation. Quite a lot of enemies are killable by enervation spam, and while normally it requires an expensive wand, in case of this change, the warlock will be nigh unstoppable.

Extra fun if this is applied to Eldritch Doom shape. Extra fun if the eldritch doom is enlarged, as proposed. I think it'll be more powerful than epic spells.

A) 21k is not expensive. You don't need to loot that much to get that amount.
B) It requires a save, unlike the others.
C) It gives 2 negative levels, vs 1d4 or 2d4 (enervate and energy drain respectively)
D) Chain would be better. Eldrich Doom requires an extra save and in most (if not all) mob clusters it would hit the same amount of enemies.
