so just done two runs of easy hydra 

was going ok, managed to decapatate the head of torment and the head of decay had say 5-6 mm of red left on its health bar and it threw up its life sheild on its self

at this point i was spliting my attacks on the stump and the head of suffering to get a champ back trying to leave the decay head alive untill i was able to focus on it 100% after the head respawned on the torment

then just after the head respawned and i got my champ back the head of decay healed to 100% health which i didnt think it could do :) Healers in this fight were scyl and godseaker so no heals could of been stolen and spread by the other head.

so just wondering if anybody else has seen or heard of anything like this ? Or i have missed something in their scrypts that lets them heal after a while?
