Enslave:

When you strike a foe for maximum damage, there will be a 1 in 20 chance to permanently enslave it to your will.

Note:
There is no limit to the number of creatures you can Enslave by the power of this Augmentation. Remember that you must divide and share experience-points equally with them, just as you do your allies, pets and steed (whether they are with you, or at a stable).
