If you manage to get the Accelerator from Supreme K enemies, which again is a must for the boss, go back to the first possible elevator and save outside. The best thing to do is to reach the bottom getting the items, then go back up and return down speedrunning with Turn-Tail. Down to level 20B: Mana Protector (Half All Magic skill attached to it) Down to level 10B: 5 Godly Dragon Tears When you return to the top, the only character here will give you items according to how deep you've gone.

Neither the items count for Treasure Trove, nor the new accessories' skills count for the skill master achievements. You will find items here and there as well (they're all chests). The levels are all very simple and contain some glowing spheres which can tell you more about the events that happened in this place. Every 5 floors (level 5, 10, 15, 20, 25 and also level 26 before the boss) there will be a no-monsters area with an elevator which can take you back to the first floor, and this is the only way out. This dungeon is made so you can only go downwards. Not necessary at all since we won't use physical attacks Sky Reaper: found in levels 16 to 19, he can drop the All-Round ring (Damage Up Lv 3+, Critical Up Lv 3+, HP Absorb Lv 3+). Prototype 3: found in levels 11 to 14, he can drop the Illusionist Gauntlet which can teach you Spell Counter 2. However, this sounds better than the Accelerator, for a purpose of strategy you don't need (actually, you mustn't have) this skill, so you can avoid spending time with these drops. Supreme K: found in levels 21 to 24, he can drop the Rose Quartz which can teach you 1 Turn Magic Cast. Fight these enemies until you get the Accelerator This is an essential skill, and he can level you up to level 80.

Steam K: found in levels 16 to 19, he can drop the Accelerator which can teach you Reduce Casting Time 3. Adamantine Kelolon enemies: they level you up (found mostly in the last levels) I suggest turn-tailing all the fights except: If you haven't reached level 60 yet, do so with the Hellish Kelolons inside the Temple of Enlightenment: here it's too dangerous. The random encounters are very dangerous, but they will net you level ups all the way to level 99 (not every one of them, but those you want to fight are). The dungeon is located here, and as you can see, it's underwater in a region of the ocean which you can only reach after some events in disc four. Keep in mind that there are no save points (and there aren't checkpoints either) the closest 'save point' is the world map outside. High level characters are not recommended: they are essential. This dungeon has extremely strong enemies, stronger than those in the Temple of Enlightenment, and the boss at the end of it is much stronger, even compared to The Immortal One fight in the Backyard (which was the strongest enemy of the main game).
