I'm very surprised if it caused fatigue of >100. Has anyone else observed this? That wasn't what I found during testing. I would agree that that would be OP.

Drain Magic is meant to allow "fair fights" between mundane troops. Nations which rely heavily on demons, undead or constructs should see Ulm as a challenging opponent. This makes a lot of sense to me thematically. The "counter" is to use a different tactic, for example mundane troops, sacreds, living summons or (best of all) lots of battlefield evocations. Or raiding!

Dominions has a lot of things like this to which there is no direct counter. For example how do you counter Wither Bones?

"Key spell" doesn't mean "endgame spell".
