I thank Angelus Dead for this thread at the DDO forums, at: http://forums.ddo.com/showthread.php?t=147352 for the information here.
I tried to put it all in one place, easy to see and use. A monk must choose between a path that allows the POS attacks or the NEG ones.

A Finishing Move is a special attack/ability a monk can use when certain conditions are met. It takes 3 special monk attacks to set up a combo attack, each requiring ki. These attacks do not need to hit an enemy. Once the Finishing Move is ready, the Finishing Move feat icon will change from a nonfunctional button into a functional one, which reflects the attack now available for a limited time. Also, your body glows when a finishing move is available to you.

Taking actions such as drinking potions, opening doors, turning levers, or nearly anything that isn't moving or punching will interrupt the combo. This breaks a combo in-progress, and dispels any Finishing Move that may have been ready.
