how do i delete a save (all my caracters)

how do i delete a save game and restart the whole thing

Your account, characters, items, gold, and everything are all server-side.

If you're serious, you'll have to contact the tech support.

i tried reseting the tutoriel but nothing happens prehaps i'll wait until it's fixed i can only play with friends because my caracter cant solo past the first map

Not a complete work around as you'll still have items and quests but you could create a new hero, delete all others plus and re-install the game. Reinstalling makes all cut scenes reappear I.e new mobs.

or if this helps with being stuck:
