Character boost

Hi, so im old returning player, last time i played i think was legion or bfa not sure, anyeways i never used my booster char, so right not ive a priest in my list “'apply boost to unlock” is this possible right now? to boost it? or i just missed that?

It sounds like you made a class trial to me. Class trial characters start at a high level but you have to unlock them with a boost later on.

with quest?

i mean how do i know if ive a booster available?

They show up as little circles in the top right corner of the character select screen next to your characters if you have a boost available.

Here’s a picture of it from a wowhead level boost guide. (It’s a bit out of date as it’s still showing as 120. Right now, the 50 boost just shows up as a “W” in the circle, and says it’s level 50 when you mouse over it. The old 110 boost now is level 48. (I’m not sure about any older boosts you might have lying around.)
