Hello.

This achievement need to finish the game with 21 characters, but i have more (27, and i don't have the pug, so there is probably more) ^^'

Can you tell me what character need to finish the game ?

Also, did there is a way to see/know what character already finished the game ?

If steam/DotE know how many champ i did (actually 8 / 21), i think there is somewhere with this information with who did it :)

You can check how many times you've won with a given character by selecting them when choosing characters for a new game; the third icon (looks like a laurel crown) counts the number of times you've won with that character:

Nice! Thanks you very much dear!
