Spells being Proc'd for NPCs attack/defense.

[HMxMisfit]

When a NPC attacks or defends it has a % chance to cast a spell.

The proc would happen when health damage is received or given.

So NPC's version of the equipment one?

Otherwise couldn't you just give them the spell?

[HMxMisfit]

Yes it would be useful for more unique enemies. It would be more reactive and less about giving them a spell to cycle through.
