I recently returned to GW2 after only playing for a couple of weeks after the game was launched. My thief is currently in the low 70s and I have spent all that time clearing PVE maps with the exception of a couple of story mode dungeons. Bottom line is I am still essentially a newb when it comes to understanding all the complexities of playing a thief.
For example, when running one of the story modes one of my guildmates told me that if I used Shadow Refuge and everyone in the group remained within the circle until it disappeared, we would all remain stealthed for 10 seconds more. This allowed us to stealth past some trash mobs. It doesn’t tell you that in the tooltip so I wouldn’t have known about it unless someone told me.
I read on another thread if you use Shadow Refuge and fire your SB thru the combo field functions as a lifetap and heals you.
Are there a lot of other examples of thief utility not documented on the tooltips?
