The steam achievement ‘No Feat Too Great’ says you need to complete 675 feats, there are not enough feats to do this with one character (there are currently 390 feats) so I assumed it would be split over alts. To check this I added up all the feats I had for my alts (by looking in the feats , under feats completed), and it added up to 683, which is above the achievement, but i still haven’t got it unlocked.
I then looked at the stats for the achievement and it says it has been done by 0.2% of players, which just confused me more… but this could have been before 1.0 as I remember achievements coming before then.
