Guild Wars 2

I was wondering how people get this 2-3 minute stealth when doing jumping puzzles and is it intended to be this long?

EDIT: just realized these peeps weren’t thieves but a ranger and a guardian. lol

theres fountains that gives this to anyone in eb

It’s an effect of an item don’t know what its called though

I see, so it’s strictly for the EB jumping puzzle then? It would be unfair if someone uses this to prevent an area from being capped.
