We need Runeknight

and sealing can be used to inturpet so you could seal away "cure" or a physical attack for a short bit so basicly it would "break the single ability" not the entire bar of it so if I seal away Cure 2 they can still cast cure just not cure 2

or it could work by locking the ability and changing what it does to its targets so cureing on a target when you sealed cure hurts them while sealng fire heals ur group

Ok, I getcha. I'm behind this.
I'm not sure how it would work in Savage/ultimate, but the idea of a support role helping others have more uptime is interesting.
