The first few kills proceed as normal with Sage reviving someone using her ult. There are 4 orbs on Fracture, giving Sage half her ult back. Assuming your team has flawlessed until now, Sage can get a 4k for the remaining 4 points required, revive a player, and both get killed. This, however, is next to impossible to replicate in a normal game, due to the extreme combinations of already unlikely situations to happen at once.
