ToME: the Tales of Maj'Eyal

Hello.
Im kinda noob in this game.
I can see any dmg from this talen tree.
I put 2 points in Vile Poisons and still dont see any nature damage.
What i do wrong? or maybe its bugged?
Deadly Poison and Numbling Poison are active.

Plz help, and sorry for my english.

It's only a chance to apply poison on each strike, and I don't think it does damage on the turn it's applied. So make sure you're hitting things enough for it to proc (it'll show up in the enemies mouse over info when it gets applied). After it's applied, it'll show up as nature damage per turn.

You also have to be sure that you have the appropriate sustains turned on for each poison you want; you can have two on at once.
