To be completely honest, this isn't a game I actively play, as my main focus has always been PC games.
That said, here's how I use the mod: I use it to farm gold and XP, level up quickly, and improve my attack and other stats. Whenever I run dungeons with cheats enabled, I make sure they don't have any rankings associated with them (although I haven't paid close attention to every dungeon). Because of that, I can't give you a definitive list of which dungeons are 100% safe.
In my opinion, the safest and most logical way to use any mod is simple: use the cheats to farm resources, make your character incredibly strong, and then play ranked or endgame content legitimately without any cheats enabled. That's always been my philosophy on how mods should be used safely.
