Inkpot End Advice

[Taqwus]

Spectres can't start with Blood magic. Randoms are both restricted to WESD, if memory serves.

Regeneration will, indeed, prevent the 1hp/turn loss that kills the Diseased, but not the afflictions. A *really* sadistic trapper might have a mage ready to cast Dome of Corruption and flee.

Personally, I'd be tempted to keep it as an invitation, if the map is suitably constricted so that you may be able to trap an enemy force there (or if you have enough assassins or leader-killing magic available to kill the leaders, heh heh...). But if you wanted to HOLD it, for some strategic value, a fortress staffed by undead would be the obvious way to go.
