Defeat Zephyr

To defeat Zephyr you need good timing. He will rush at you and wont stop until he hits you unless you jump over him so use the double jump. An easy way to attack Zephyr is the Gergoth soul. Use it while Zephyr slowly walks toward you. Another attack Zephyr has is to stop time. He will stop time and set knives above you. Move carefully when time starts again. He will also throw knives horizontally and diagonally from the ceiling so you will have to dodge a lot.

Beat Balore Easier

To beat Balore easier, get the Manticore soul and get the Battle Axe or the Bhuj. You attack once with the axe, and the tail will attack twice doing much more damage.

Secret Monsters

There are three secret monsters (the Yeti, Mothman, and the Flying Humanoid.) To get the Yeti you must first get the Waiter Skeleton Soul then go back to the very beginning of the game. You will see him walking in the background. Toss the curry and he will come up where you can attack him and gain his soul. You will need the Rycuda soul leveled up to at least two to get Mothman. Go to The Pinnacle to the area where there are two final guards and a light in between them. Strike the generator next to the light with Rycuda and Mothman will appear. For the Flying Humanoid, you will need the Mandragora soul. Enter the room in between the Zephyr Boss room and a save room then use the soul.

Defeating Dmitri

To defeat Dmitri in your first encounter with him, use the Axe Armor bullet-type soul only, because any other soul you use will be copied and used against you. Use the Axe Armor until you hit him once. He can now only use that attack. When he uses your Axe Armor, go in-between the attack and himself and hit him with any heavy weapon once. He will then dash backwards and attack you again. Repeat this trick until he dies. Do not get worried if he hits you with the Axe Armor, because it will not hurt much. The best way to defeat Dmitri is to use the Cave Troll Soul and let him copy it. The Tongue will go to the end of his arm.

Defeating The Iron Golem

Use the Imp soul. It switches HP damage to MP damage.

Defeating Abaddon

When fighting Abaddon, equip Death as your Guardian Soul. Death's scythes will attack Abaddon repeatedly for about 30 to 35 HP of damage per hit. Death's Soul also will destroy some of the locust swarms that Abaddon uses. Keep dodging Abaddon and the locust swarms, and use Mind Ups or Mana Prisms to keep your MP filled. Use potions or food when your HP gets low. When using a combination of physical attacks and Death's Guardian Soul, it will not take long to take down Abaddon.

Easier Boss Rush Mode

Activate the Devil Soul and use the Valmanway Sword. You will take down all the Bosses in less than five minutes.

Best Ending

Use the Paranoia Soul to fight Aguni. Collect the Magic Seal then return to the center of the castle. Have Mina's Talisman equipped when you enter the Boss door, then complete the game.
