Force Choke is a dark side ability learnt at level 9, by any of the 3 Jedi classes in Knights of the Old Republic. The prerequisite of this ability is Force wound.
This power constricts the throat of a target at range, stunning and inflicting 2/3rds of the attacking character's level in damage every 2 seconds for the duration (6) seconds. The target also suffers a temporary (24) second -4 penalty to Constitution, Dexterity and Strength. A successful Fortitude save at DC 5 + the attacking character's level + the attacking character's Wisdom and Charisma modifiers results in no effect. This power does not affect droids.
