If I am not mistaken Tree of Savior is protected by xigncode3. Other posts by apoc have implied that xingcode can be a challenge to get around. Seeing as it's a style similar to diablo / Path of exile could be interesting.
Xigncode's been bypassed pretty easily. There's even loose source on a few other sites that'll explain the bypass.
Stopping Xingcode from initializing is easy yes. but if the game has the heartbeat that's another story. Personally i haven't looked at the Tree of savior stuff so i don't know if it has the heartbeat.
I would also Love to see a Tree of Savior bot.....would give me something to do and play around with while wiating for my WoW account to get un suspended =D
