DP in PvM

I was wondering if undead creatures are immune to deadly poison (like liches, lich lords and so on). I understand dread spiders and poison elementals are logicaly immune but what about the rest? Dragons, Balrons?

Dragons arent immune, about balrons normal poison doesnt apply, the one casted at least.
DP should work great on orger lord too.

Immune or not, anything that casts will very quickly cure itself.

I use DP a lot on casters. I don't think undead are vulnerable to poison but DP is great because it isn't always cured right away and the mob's will always cure poison before casting any other spells.

This. Mob curing = mob not casting on you.

I find this quite usefull since both my orc rogue and my wifes orc lack magery. Cure casted instead of Corp Por when against a lich might be the difference between life and dead. That's why i'm so interested.

Good info sirs. I learned something today.
