GA + Rabbadon combo= Extra hp on revival
I just got a match where an enemy Varus was equipped with GA, Rabbadon and RFC. On revival, he was almost fully healed. Note that lvl. 2 Varus has 900 base hp and GA heals back only 500, thus the increase from Rabbadon. Might be a bug, might be intended, but peeps are using/ abusing it. :)
