Heya
While messing around in AB earlier today I found this bug, im not sure how it 100% works ill just explain how it worked for me
Basicly i summoned Dancing rune weapon and casted runetap(note i got improved runetap and Glyph of runetap) and i first got my own heal of runetap but 2 secs after casting it my runeweapon healed me 4x for 10% of my hp(so a 40% heal) im working on a screen atm will try to post that
Enjoy=)
