Where to find Dark Inferno in KH3?

In order to find this secret boss, you’ll first have to finish the game. Once you’re done with the main story, the Battlegates will open all across the game world. Dark Inferno is hidden on the other side of one of these portals. Travel to the Keyblade Graveyard and look for Battlegate 14. Enter it, and the fight will begin.

Keep in mind, this is a really tough enemy. He has a 3 star difficulty, and you’ll have to fight him without the aid of your buddies. He has, like, a gazilion health points and his weapons are really long. It’s going to be living hell if you haven’t mastered your combos.

Dark Inferno rewards

If you manage to overcome the dark devil, you’ll end up with a great accessory. It’s called the Crystal Regalia, and it will increase your strength and magic by 5 each, your AP by 16, and will give you access to the MP Hastega ability. The ability is used to replenish MP, so it’s a great fit for any character build that relies on casting spells.

We’ll keep exploring the game, and if we discover any more secret bosses, we’ll let you know promptly. Stay tuned. If you need help with other stuff in Kingdom Hearts 3, we’ve written about orichalcum ore locations, the mini-games, Flantastic Seven challenges and many other difficult, tedious or simply poorly explained things.

      I beat him before sephiroth he might be the easiest super boss

  3. H

    No kidding. I stumbled upon Battlegate 14 just in passing, fought the dude, killed him first try and didn’t realize he was even supposed to be “strong” D:

  4. K

    he’s not a tough fight at all, he’s probably the easiest optional mega boss in all of KH, if you are lvl 99 he barely can take a pixel outta your health bar before you destroy him

  5. M

    Ha, a joke of a “super boss”. Beat him first try and at lvl 70

    1. S

      Lv. 60 here. Beat him with a few elixirs.
