as the title says. Was beating up some Rift Cultists and noticed the Temptress taking full damage from tease attacks. Kiyoko and Cait have roughly the same Sexiness in their current sets (31 for Kiyoko and 29 for Cait) and their Teases hit for about the same, and despite triggering the perk effect, there was no half damage reduction.
The perk in question:
Kiyoko's Tease that triggered the perk and should have been halved
Cait's normal Tease
