It reflects a single target spell back to the caster once per day. Its an armor. It was made for npcs before being looted.
Yup. For one spell once per day. To relativise, they are level 14 now. So it's not like they didn't had access to 15 different game breaking options. But I was sure that the character would die... for like 1 session before one of the 5 ways of bringing someone back to life would be used.
It is hard to make a decent challenge for high leveled players. If I can make them nervous, even if they win easily I call it a DMing win. And I certainly managed that last night so I'm fine with it.
Seconded. Did it bring them back? Some kind of counterspell? Teleported them to the Astral plane?
