Artifact "feature" and some late game stuff

Astral Shield is a powerful spell. I'd rather have a slight chance of losing the entire battle and my god, than the greater chance that the opponent swarms and kills my god.

That and the fact that if you are going to cast Astral Shield, you had better have the ability to kill them. This works well with tramplers or anything with high strength, since Paralyzed units have an effective 0 Def.
