I have a question to ask, first let me explain a little bit.
My friend and me are playing tos on 2 different pc, with 2 different steam accounts, but sometimes he can’t online to do missions and dungeons, so I’m thinking about if i can login to his steam account on my pc to help training his chara?
If the case above is possible, I am concerned about if i login to his steam account to my pc, my in-game data(character info, lvl, game progression) will be gone or overlay by his in-game data. And If I succeed switching to his account to train his chara, afterward I switch over to my own account, my in-game data will still be there or not?
Basically I just wanted to know our tos client in-game chara data is binded to the steam acc/tos server or local game client.
Thank you.
