Bandit's Guile

Bandit's Guile is a rogue talent located in the Combat tree. It gives Sinister Strike and Revealing Strike a chance to grant a series of buffs that increase damage to the target by up to 30%. You first gain Shallow Insight (10%), then Moderate Insight (20%), and finally Deep Insight (30%); after Deep Insight drops off, or when you change targets, the cycle restarts at the beginning.

Tips and tactics
To maximize damage, try to use your offensive trinkets and cooldowns when Bandit's Guile has peaked at 30%.
