It would be nice if this page answered the question "What if I have multiple items/attributes that each grant Onslaught, each with a different duration? Which duration is used? Or do they stack?". Another question is "Is there any way for me to increase the duration of Onslaught (ie, do the Skill Duration passives impact it)?" SonOfSmak (talk) 02:01, 10 September 2015 (UTC)
- Like most other buffs, Onslaught doesn't stack. Gaining Onslaught while already having Onslaught will simply refresh the duration. As for your second question, the article for Skill effect duration already answers it. —Vini (t|c) 16:10, 10 September 2015 (UTC)
- Well, it didn't really, but hopefully it does now. Skill effect duration only affects the duration of a buff if the buff was granted by a skill which has the duration keyword. Non-skill sources such as uniques are never affected. Innervate, lacking the duration keyword, should not be affected by skill duration nodes if the system holds but I have not tested it. --Qetuth-(talk) 00:14, 11 September 2015 (UTC)
According to https://pathofexile.gamepedia.com/Watcher%27s_Eye page Watcher's Eye cannot grant onslaught.
