Im testing currare + amatoxin + po runes.
Lets say my dmg is 100k with currare and ama, when im adding po runes into weapon its instead of bbosting - halving tooltip damage. Any idea wtf?
Different sources of poiosn dmg on weapon stack the following way: their dps is added together, and their duration is averaged. The tooltip shows damage per attack, so when you add a poison rune, the duration of the total poison goes down because of the poison runes low duration, which means the damage done by a single attack will be lower. The dps will be higher tho.
