Elemental Damage

[Side]

Does additional elemental damage stack from different sources of the same or different type? Like from flame weapon and the dragon warriors extra damage?

I can't remember because it's not very often you come across this case.
But I think it does?
Ping molag or BMD. I bet they might know for sure.

The elemental damage from Darkling Weapon will stack with any elemental damage on a weapon, but it will change the VFX. Whatever kind of enchantment is placed upon the weapon last is what the VFX will appear as. So if you have a 1d6 flaming weapon and cast 1d4 cold damage from Darkling Weapon or Annointed Weapon, the damage will stack, but it will have the cold VFX.

Also keep in mind that elemental damage does not multiply on a critical hit.

[DM Fugue]

Elemental damage doesn't stack.
A 1d4 fire weapon with a flame weapon on it will do 1d8 fire only.
They don't get multiplied in crits either.

However Physical damage does stack up.

For 1d4 piercing stacks with other sources of 1d4 piercing.

At least my slings with 1d4 and the Druidic spell Thorn Skin do.

[DM Fugue]

Physical damage normally doesn't stack.
a +4 enh longsword is no different than a +4 enh longsword with 1d4 slashing.
Your sling has 1d4 piercing on top of the piercing damage from thorn skin ?
