Re: Duel Priestess - Horror Mark
 

You definitely should. The horror marks are light, and I'd reckon your chances of getting marked are about 10% per turn. They're extremely cheap, raise research plenty, and will end up killing your mages extremely slowly.

Give them to your cheapest, most disposable mages, so even if a horror randomly attacks or if a blood nation chucks horror-summons or ashen angel at you, you aren't losing anything expensive. If you've got good enough troops lying around with nothing better to do, give the mages a bodyguard capable of taking out a small horror to help them out. Although troops that good would usually be better employed killing your enemies.
