Can Sett use his ability to remove a buff when he is exhausted?

Ruling: Yes, Sett can spend his buff while exhausted, but it gives +4 Might instead of +8.

Nuances:

• If Sett is buffed again (such as by conquering) while exhausted, he can spend that buff for another +4 Might
• The reduced effect (+4 instead of +8) applies because he is exhausted
