There it is. The final boss of the game. Unlike the previous four bosses, this battle is actually quite hard as the boss hits like a truck while also inflicting ailments or binds. I would say don't try to fight this boss unless you nearly or reach level 70, have nearly or the best gears, and bring the necessary items, explained below.

This boss doesn't have an opening move. It just alternates between Freeze Breath, Thunder Howl, Dark Claw, Crushing Claws, and Panic Crush, all of which hit some or all party members for moderate damage. It also can cast Ruinous Roar, which gives buffs to both the boss and you. After 5 turns have passed, it'll activate Grudge Miasma. This is a field effect in which in the end of the turn, all damage dealt by both you and Eternal Tyrant will be combined, then a quarter of that number is dealt toward both sides. The boss takes full damage, and the damage to your side will be spread to all party members including turrets/summons/wraiths. After two turns, it'll use Miasma Drain which cancels the effect, and also telegraphs for its ultimate move, Burning Miasma, which deals huge fire-based damage to all party members. The surviving characters also has their defense reduced by 30%, which pretty much spells game over as its next move can easily wipe out the remaining characters while you are trying to recover. Afterward, it'll use 5 random moves again which repeats the cycle.

For the strategies, this boss is weak to sleep ailment, so bring a few Sleep Gas, buyable at the shop for each Sharp Batfang, dropped by Hypno Bat in 4th Stratum. Use your first turn to cast sleep, then cast full buffs to your team before using high-damaging moves to wake it up. Ice element buff is also good since the boss is also weak to ice. All of its random moves hits for quite a pack of damage, so if your party members don't have high defense, healing may pose another trouble, hence you need to level up. Freeze Breath and Thunder Howl has Ice and Volt element, respectively, so you may want to use some element-mitigation items/skills. If it casts Ruinous Roar, you may want to dispel its buff by using Laudanum, buyable at the shop for each Thick Stalk, a common taking material in 5th Stratum. After it casts Grudge Miasma, you may want to hold off your best deal-damaging moves unless you are ready to take the recoil. Use this period to reapply buffs. After it casts Miasma Drain, try to bind its head, inflict sleep, use All Mist to reduce the fire-based damage, or activates Aegis Shield / any fire-nullifier/absorber skills. The normal fight usually lasts for 2 cycles, so you need to deal with Burning Miasma twice.

Defeating this boss nets Shadow Dorsalfin. Fortunately it doesn't have additional loot so you don't need to worry about it. Thankfully Atlus doesn't make this fight even more annoying.

Enjoy the ending and then save the game to mark it as completed. This is my Guild Card stats after defeating the final boss.

However, the game doesn't end yet, as you can progress deeper to the optional stratum, the 6th Stratum. You can also fight the optional bosses later. Remember the Primordiphant in 8F? You'll need to fight it later.


Load the game and head outside of INN. A Town Crier informs that you need to report your achievement to Ramus, so head into Council Hall. Ramus gives Arcania's Orb as reward for conquering the labyrinth. This accessory gives HP +50, TP +50, and 10 points to all stats so definitely equip this accessory to your character.

Now return to 25F and continue to head north of the last boss' battlefield to find another door. Arken shows up again, on its true form this time, congratulating you for defeating the evil. She gives you Yggdrasil Ring and Yggdrasil Mythril as reward. Yggdrasil Ring gives 30 points to STR and INT, so equip it to your main attacker. She also makes another request if you want to escort her until she reaches her destination. Choose the first option to accept it, then open the door and head straight again to start your journey in 6th Stratum.
