I’ve got a rank 20 Temptation relic attuned to one of my creatures. Rank 10 is “After the bearer Attacks an enemy, the enemy Attacks itself. The amount of damage dealt is based on the bearer’s attack.”
I’ve had my creature with the relic attack and not once have I seen this ability happen. The target creature takes damage from the attack (and doesn’t die) but the enemy never attacks itself after.
Unsure if Rank 20 ability works as I haven’t gotten the Rank 10 to trigger.
