Was wondering what happens if I poison both weapons with the same poison? Say I put lethal poison on both blades and both hit. Can somebody be double poisoned so both tick?
nope, they wont stack
In fact it won't stack with another assassin's, either. If two infiltrators attack the same target, the last, best poison of that type to hit him will cancel out any others.
the DOT poison will stack with the Alchemy DOT proc's/charges because they're on different resists, and ive heard that the DF weapons that proc DOT's will also stack with both of them because they're on heat resist
