I'm not sure why Grindstone insists on healing, personally. If someone wants to trudge through the event bruised and bloodied, what difference does it make?
In general, instantaneous healing pretty much removes any real danger from most situations, and that's a bit inconsistent with how the setting is presented, where NPCs do indeed fear for their safety. So magic "poof, you're all better!" healing is probably very rare. In the Conjurer questlines, healing comes up many times, but it's never as simple as wiggling your fingers and suddenly someone's okay. It's usually trying, risky, and not always guaranteed to succeed.
