Sniper Training is a hunter talent in the Survival tree which increases Kill Shot's crit chance, and boosts other damage after the hunter stands still for a while.
After standing still for 6 sec, the hunter gets the Sniper Training buff, with the noted effects. This buff lasts 15 seconds, during which the hunter may move around without canceling the buff.
