Always +15 gold when attacking inhibitors with Spellthief's Edge
Happend in my game when I got autofilled support. When I attacked the inhib, I never lost stacks of my item and always got +15 gold for every attack. Happened at around 32:00 min. I accidently used Zhonyas when I wanted to place a ward just as the inhib respawned, maybe that had something to do with it?
