Shattered Kingdoms

Why do they cast these spells during combat?

Maybe they don't like being attacked, ever consider they do not like to die?

Faerie Fog isn't offensive whatsoever - it's a waste of a spell to cast during combat.

All it does is reveal hidden or invis characters and cancel the effects of sneak.

So I ask again, why do they cast it during combat?

I do not know whether it dispels a certain appearance-altering cabal spell - it would be extremely funny if it did.

I don't know for sure, but this is my suspicion:

The spells a NPC casts during combat are selected randomly from their list of available spells. Thus, occasionally a NPC that can cast faerie fog will select it from their list of spells to cast. The same reason a NPC that can cast edrain or harm will occasionally cast fly instead, even though it has no offensive value whatsoever.

Bottom line:

It's a round where you aren't getting owned by offensive spells. AKA, a gift horse. Try not to look it in the mouth, eh?

Damn, Nath, shut up. We don't want this getting looked into - for the same reason I don't want it looked into that priest NPCs will occasionally cast sanc during battle instead of a flamestrike/confusion. [REDACTED].

Faerie fog also cancels camo too.

What -should- be looked into, however, is that every single caster NPC, including reknowned warlock and shaman trainers are suddenly priests, casting harm and hold person...

Faerie Fog lowers magical protection.

Faerie Fog also makes a target easier to hit.
