Crusader holy sword acts like spell on a non-caster kit.

[Bladesong]

Holy sword causes attacks of opportunity, requires concentration checks, on a kit that loses Spellcasting so it has no need for concentration nor ability to cast spells.

If it cannot be converted into a feat is it possible to remove the AoO & Concentration checks ?

[Winterborne]

It's converted to a spell-like ability, which while not a spell, still has the downsides of a spell. I am fairly sure it's working as intended.

[Bladesong]

That converts it not to a buff but a berserk-like ability where we have to weigh if it's worth the risk in activating casting the feat versus potential death from all the AoO.

This looked like a really cool pure class to meet all the min-maxed multiclasses I see but having to choose whether or not I use the main feature of a class while I understand mathematically it's sound but as far as playing it's like a Cleric after being the sole survivor of a battle thinking "I could resurrect the everyone or I could play it safe and run home before more monsters arrive"

So now I have to put points into concentration taking away from Heal and any chance at having leftovers for RP skills. I'm sorry I'd rather retire the character , can you at least please state on the wiki it IS a spell not "spell like" and that using it will incur all regular spell penalties such as getting half your health smacked out of you by an angry minotaur (i was lucky it was only one).
