When I entered the Quest shop, I apparently activated the achievement Unlocked Quest Points. Didn't know this one existed. I can't find it in my achievments list and the description is also a bit vague 'Have quest points'

Where can I find this in the achievement list? Is there a tier of it?

The achievement is called "Quest Points" and is found in the Quests section under the Games category.

This achievement does have tiers with the highest tier being 100. I know it is usually triggered when you enter the Quest Shop.

Thank you I found it. It was listed under 'completed' lol
