Use Dungeon Finn for sweeping through early game rounds with minimal investment as he and his upgrades are both cheap and powerful. That being said, Dungeon Finn can scale decently enough in the lategame, notably with his Inferno ability dealing its damage multiple times with enough attack speed. Regardless of what attack the player prefers focusing on, Attack Speed increases with Finn Sword and trinkets such as Baker's Shard and Bubblegum's Hair will be important.

His Battle Moon and One-Two Combo attacks do not benefit from damage increases but will benefit from bonus damage, so Engineers Blueprints is also recommended if opting for a build strengthening the Battle Moon. If prioritizing his melee attacks, having some range trinkets such as Glasses of Nerdicon or melee-specific trinkets such as Tiger Claw, Powerometer, or Vorpal Hand will be useful.

If prioritizing Inferno instead, a mix of Attack Speed and Cooldown reduction is recommended, as any damage increases will be negligible for Inferno. Baby Tooth and Cosmic Gauntlets provide the most benefit for spamming this ability, while Warpaint Mud excels the most in Send in the Clones.

If considering purchasing Dungeon Finn, whether for actual money or with Martian Crystals, and cannot purchase the entire Character Bundle, it is recommended that Tuxedo Jake and Hunter Marceline are prioritized instead. Hunter Marceline scales very well in the lategame and Vampire King from her adventure is one of the best allies in the game for Martian Games, while Tuxedo Jake provides useful buffs and Lady Rainicorn from his adventure can be useful on certain maps with poor placement spots for towers. Dungeon Finn on the other hand is not nearly as gamechanging as the latter two, and his the ally from his adventure, Train Boss is considered a very weak ally because of slow attack speed, weak damage, and low utility.
