Hi! I wanna report a bug I’ve encountered several times during the PTR.
Whenever you have Simulacrum active with the new set, and you enter a new Rift (normal ones, not Grifts) they will stay active, but not provide the damage reduction.
It’s very easy to test, because you can stack up on Bone Armor and get hit. Your HP will drop dramatically, or you’ll simply die 'cause of the hit.
Also, if you re-cast Simulacrum, the damage reduction will then be provided.
