I fought this node with Omega Red. The node reads “when activating a special attack they purify any bleed debuffs on themselves and gain a permanent passive prowess increasing special attack damage by 20% for every bleed purified this way. Max stacks - 20”
You will see in the video that I used both special 1 and 3 with omega with bleeds in and did not purify any of the debuffs.
Please take a look. PS - Hi Rich!
