Spirithost Bug
Bug Status: Fixed! (Thanks)
System: Windows 7 (BlueStacks)
Patch: 1.7
Spirithost skill claims: Attack 1 enemy. Heals by 50% of the damage inflicted (based on attack).
I inflicted 10,505 damage to 1 enemy but, was only healed for little over 7% of the damage. (???...)
If only use the attack stat currently: 1241 (50% of that would be 620.. closer but, that's not what was inflicted.)
I think overall this is either a bug or bad skill description. I added some screenshots below:
