HP: 37, AC 22 until he acts
Depending on the status of the various orcs on his turn (In order), Kylest will. . .
Is Orc III alive? 5-ft Step (W19). Attack!
Is Orc II standing right next to me? Attack!
Is Orc II continuing to assault the victim? Move (V17). Attack!
If none of the above apply, Kylest will attempt to charge Orc I, if there is an open path.
Failing all that, move somewhere and swing a big piece of steel at something else (preferably something green . . . sorry Oog).
No move or 5-ft step . . .
Attack +8, 2d6+4, 19-20/x2 . . . AC 16
Move 10-ft or more
Attack +8, 3d6+4, 19-20/x2 . . . AC 17
Charge
Attack +10, 3d6+4, 19-20/x2 . . . AC 15
I think that covers anything except flavor text.
With undwarfly speed and grace, Kylest darts forward into the fray, his sword raised high in a very dwarfly display of orc-related violence. His sword swings firmly even as he keeps an eye out for the orc's intended prey.
