Sheltron: Kind of cool, short cool down, restores MP, nice for big physical hits if timed perfectly. Would be nice if auto attacks didn't occasionally knock it off.

Divine Veil: Pretty cool, nice when it works as intended.

Clemency: Seems like a bit of a flavour skill really. Still waiting for the moment when it will come in really useful, although I think it will one day.

Royal Authority: Boring but it does the job.
