If the Helpful Mander casts donate power on you, and in the same turn is killed (this only happens if you go first), watch how the pips given to you are suddenly removed.
Well I am sure it was just a glitch, but I wouldn't mind it staying that way. Gotta respect your Minions and keep them alive! (Course this isn't really directed toward you so much as general public)
I wonder will the same thing happen if the one who cast Donate Power and is killed happens to be a human wizard?
