Guild Wars 2

For Seasoned Toymaker achievement you need 18 achievements.

Can I do Toypocalypse Survivor 5 times, and then I have 5/18 for Toymaker?
it says infinite

If an infinite one counts at all (not all do afaik), it will only count on the first completion. Eg 30 songs for Choir Bell would only count for the meta the first time you did 30 songs, though you’d be able to repeat infinitely for gifts.

I’m pretty sure that none of the infinite achieves counts towards the meta, but as Donari said, if it counts only the 1st time will.
