This exploit is truly awesome, making the Mesmer an even more fun class to play.
When you use the skill “The Prestige”, you can hit escape right before and cancel the skill, making the cooldown go from 30 seconds to 3.5 seconds. This is almost a 90% reduction in cooldown allowing for an almost constant stealthing Mesmer!
You can also combine this with “Prismatic Understanding” for an additional second of stealth time.
To get “The Prestige” simply use a torch on your Mesmer, it is the fourth weapon skill.
