Is Shadow Blast bugged?

Its most likely the mr check as most other AoE spells dont require one.

Equip your shadow blasting mages with penetration items for increased effect.

You might also consider Plague if you have a lot of undead troops, or Banefire for those who have easy access (although I usually find that, save for sieges, the Decay effect only really kicks in when people are starting to run anyway - but it's still nice not to have to face them later).

The decay effect of banefire is nice but its the huge damage that makes it good imo

Yeah, it definitely kills whoever you aim it at unless it's a pretender, which was the basis for my recommendation - should probably have made that explicit.
