Funny story about trying to dispell my own spell:
Playing EA Mictlan and I've got Astral Corruption up. I've got a ridiculous blood income, so I figure I'll put up BoT and stick boots of youth on all my guys. I cast it with a vampire lord so that it won't be immediately dispelled due to a doom horror killing the caster (immortal vampire immediately respawns, keeps the enchantment up).
.
.
.
Oh crap, boots of youth don't protect against BoT
.
.
.
Double oh crap all my mages are old and dying like flies
.
.
.
Tripple oh crap, I not only have to get this caster all the way from my capital into enemy territory, I also have to get him out of my dominion which I've recently been pushing with blood sacrifices!
So I get him all the way over to the edge of my (large) dominion, hemorrhaging mages the whole time. I tell him to attack the first enemy province he can reach...only to have my opponent coincidentally teleport in to attack the province from which I was attacking - inside my dominion! Stupid count now respawns all the way back at my capital. I get him all the way over to the edge *AGAIN* and attack as fast as possible - but the damn enemy PD makes a bad moral roll against the count's fear aura. OMFG WON'T THIS GUY DIE! Finally did kill him after that, having already lost most of my mages.
