This is one of the few features, that I personally think are distinguishing Lunar/Badlion from forge mods for dungeons. Odin's Spirit Leap Overlay (Image) is very useful and has the Classes always in a certain order (this is important, without this it wouldnt really matter!). It's a menu that redirects your clicks so it's technically not a cheat. They also have click redirecting Terminal Solvers making you not pick up an item frame each time you click something in order to solve the terminal (essentially reducing the difference ping makes when solving these). Theres also this really cool terminal practice minigame. The last 2 features I'd say are noteworthy are Bettermaps scuffed secret waypoints (better for advanced players, making the view less obstructed than f.e. Dungeon Room Waypoint's) and maybe some party messages that automatically send when at certain positions (for ee2, ee3, goldor tunnel, ss, melody etc.).
These are in MY opinion the legit mods that make the clients currently worse for dungeons with the primary focus being on the Spirit Leap Overlay.
