been playing for almost 3 weeks now, what I'm doing:
- I mostly use the modded version for farming scenarios in hell mode to max my monsters or lvl up fodder
- I don't use modded version for guild content, I don't wanna risk it even if it is "suppose" to be safe (do it at ur own risk)
- don't attempt to finish faimon boss level until you are at least lvl15 and finish it after 2-3 min to be safe
- ask for mentors and use their monsters in high levels
- don't go up too much in clearing dungeons and TOA => ANYONE can see your profile and your progress
- don't go up too much in arena, I stay at 1050-1150
- don't take the acheivements reward because they also appear in your public profile (ex: you are lvl10 and finished hell mode => doesnt make sense)
- most important one: you are playing a modded version, be prepared to see that lovely message at the start of the game any day :D
