Ok here's what i've noticed while using glint bow it's proc cluster bombs targets environmental pools like shaman pakuna's lava pool,pets with pool Aa's,mage's clock, barrels, poison pool at arena,rogue's veil, and lastly at rengol maps thumper, the proc targets the gems with mine cart instead of thumper and it also proc thumper's puke slime(don't know what to call it) LoL anyway please take a look at it and check with your files etc..
