"Necropolis" - changes to creatures of levels 6-7.

If I understand the mechanics of this ability correctly, I agree that it shouldn't have immunity to certain effects – then we can simply reduce the Banshee's defense by at least 5 (45 defense with 200 HP is a lot), and with a 50% chance of the ability triggering, it will be more effective than incorporeality (although when it misses, we still get a counterattack, but here we don't, and we move away to a place where we probably don't want to be – the units don't listen to us). Perhaps we can reduce the Herald's health by another 10 HP (by the way, don't forget that dragons had 160 HP and fewer useful skills – so we're already becoming quite powerful with this "presence," let's not overdo it).
