Ah ok... Well, are there a good amount of types of poisons you can make and etc? I honestly do not mind weakening myself a bit if I can make use of perks for Alchemy if I can make good enough poisons. It is either that or I go light armor I guess. Using poison to kill victims just seems more like it makes sense but if its just going to be tedious and not help at all i wont bother.
There are quite a few poisons you can make that damage stamina, health, and magic. Paralyze is great, as are several others. Of course, the higher your skill and the more perks you put into alchemy, the more potent your poisons are. My assassin hasn't spent nearly enough time on alchemy, as he's comfortable buying potions when he can (and finds plenty of decent ones during quests). The Shrouded gear from the Dark Brotherhood also keeps his archery and sneak attack power pretty high. He does run into trouble in close-quarters fights, but the
Marked for Death shout helps to weaken his enemies.
