I read the info/ lore/ description and I still find it misleading. Lets say for sure the self casting bane is working as is intended. If my character has been playing as a follower of the absolute through dialogue options (side note they have), how would a player know if they met those requirements to wear the gauntlets? Unless I missed a background selection or an option in dialogue there hasn't been a clear indication that I am a follower of the absolute unless an NPC has stated it. Yes there is a possibility that option could be further into story; but for being an item that is in act 1 it seems odd. I haven't played the DOS series, but in other rpgs they make it pretty clear that if the player hasn't met X requirement for an item, they'll suffer the negative effects.
Either way if this is the case, and the gauntlets effects are for both wearer and target, its bizarre to me that it would be a reward.
