Steel Dervish

Your training gives you the precision and control to drive every strike deeper than the last. You gain the following benefits:

Widen the Gap. When you hit a creature with a weapon attack that you have already hit with an attack on this turn, add +2 to the damage for every preceding attack that hit the same creature.

Chaining Strikes. After killing a creature with a weapon attack, you may immediately move up to 10 feet without using any of your own Speed or provoking opportunity attacks. If you attack another creature during the same turn, after killing your original target, you may treat the killing blow as your first hit against the new target for the purposes of calculating the bonus damage from Widen the Gap.
