Holy Locket shoots players as a target even with global pvp turned off, Can kill them if healing taken is strong enough and ignores their armor. (modpack Allthemods 10)

Used Iron's Spell to heal myself and the healing bonus was so high a friend nearby got hit from full health to 0 and died.

Hi. Thanks for the info. Will be potentially fixed in the next update. You can reopen the issue is it will still appear for you after the update.
