The player of Grot, our Fighter, turned up for tonight's session, but had to go before the session started. He left his character sheet so that someone else could play Grot for the evening, and that someone else was me. Normally when a player is not present for a session all sorts of things can happen to his character. In this case, I played Grot pretty much true to type: I charged Grot in to battle at the start of every fight, remembering to use his Leap Attack, and I used Power Attack at every opportunity, missing several times because the Tao of Power Attack doesn't lie.
One change that I brought to the character, to his advantage I would say, was that I remembered Grot was wearing a Cloak of Displacement. Grot avoided damage twice because of this, as his foe swung at an image of Grot and not the Fighter himself. I hope this new facet of the character is carried forward in following weeks.
Of course, some things never change. One immutable fact about letting someone else play your character is that you'll never get it back with the same number of hit points. Or, if you do, it won't be for long. Grot's player will come back next week to find his Fighter only just above single-digit hit points; not only that, but they cannot be healed normally. My work is done.
