I'm trying to prepare for the patch saving up gear and planning on what to do. Using a SS still, I'm a tad confused involving both of the fire runes for the skill. Since they are both DOT attacks and don't land critical hits, how is the IAS increasing the damage dealt by the hydra? From what I understand, all the hydra is doing is hitting more enemies quicker, but the hydra's are not dealing more damage from IAS increase . From what I read people are saying hydra's attacks stack now? This is what I don't understand and am looking too find out.
