To stop turtiling In FFA matches of 4 or more that the Mage with a killing blow gets a reward of Damage back and mana. Say it's 4 way FFA and Mage 1 gets 2, but almost dies in the process, so the best way to avoid that is to give the killing blow Mage a mans boost and damage reduction. I.e all the dead mages remaining mana (upto a cap maybe) to the killer, and the killing Mage gets damage reduced all the way back to zero, or maybe half their current taken damage or equal to the damage done on the killing blow ( or possibly the higher of the last 2 mentioned).
It's a balance between breaking the game, but it seems important to try to dis-incentivize turtiling.
