Ermor vs Pythium Hydras, help!

[llamabeast]

Oh yeah, get slingers! They're really good against hydras I believe, and very cheap.

Slingers and/or flail-wielding gladiators should make short work of the smaller heads, communion up to power of the sepulcher if you can and toss that on your undead spam as outlined earlier.

Edit: Reverse communion for animate and the master will probably wind up spamming 0 fatigue holy once his animate skeleton script runs (and the slaves are fatigued) so you aren't risking the slaves.
