Shameless self-promotion:
In a dungeon idea I did, I made a similar idea. However, instead of purifying the Paladin and taking the one unique thing that the Priest has away from it, I made an effect called Purity that makes the players immune to debuffs.

From what I could tell, this seal was seen as one of the idea’s premier items. I received tons of praise for it. Overall, people liked it.
This idea, though, just takes the Purify effect and slaps it on a seal. It doesn’t do anything new. It seems pretty weak, by the way, as it gets rid of Healing and HP Increase entirely. Also, as others have said, the sprite looks like Gcookie. However, to me, it looks more like the Realm Gold icon.
Overall, not a great idea, but it can be improved and be great. 4/10.
