Guild Wars 2

If I delete my revenant and create it again in another race, my Progression Booster Pack comes back to work again.

Presumably you’re referring to the Level 80 boost.

“This boost will immediately raise you to the max level. You can experiment in the Silverwastes before you need to commit to expending this item”

“Try playing your profession at max level in the Silverwastes before committing to make the boost permanent for this character or to use it on another character.”

As long as you don’t leave the Silverwastes or accept the changes to make that a permanent level 80 you can delete the char, make another char and use it again.

No it do not

I already used the item. Thank you all.
