well, with it being like most other absorbs thats balancing enough right there (lolabsorb spells >_>) considering decay rate 15% is fine an nethervoid overshooting it wouldnt be such an issue since haste caps+decay, recast/cast speed are the things to take a look at, should we be able to cast it to keep it up 24/7 or should there be a cooldown on it should it take time to cast cus right there its negatively effecting us(possible balancing act) how much mp should it cost etc

i really want to see this spell in game but im not keeping my fingers crossed on it
