To get the bell you need to get the Hippogryph Soul in the abyss, go to the room in the Dark Chapel with the three bells and use the Hippogryph Soul under each bell. One of them will drop the bell that you can sell to Hammer.
In the Demon Guest House, there is a small room with a bed, a waiter skeleton, and a chair in it. When you walk in, the skeleton will throw curry at you and run into the wall, killing itself. Walk in front of the chair and press Up to sit in it. Wait approximately fifteen seconds and a crown will appear on the floor in front of you. It cannot be equipped and you cannot use it. The description reads "5000 points".
In the left part of Subterranean Hell, there is a gold slot machine door. If the last three digits of your gold are 666, the door will slide back, and you can get the Gold Ring. With the Gold Ring, you can get more money from enemies and candles.
In the Clocktower in one of the rooms with a lot of spikes, there is a small area with no spikes that is very difficult to reach. Use the Bat Company Soul and land on the spot, then crouch. The Konami Man will fly by, which you can catch and sell to Hammer.
In the Condemned Tower, there is a gold slot machine door. If the last three digits of your gold are 573, the door will open, revealing the Shaman Ring. This allows you to gain experience faster.

Activate the Devil Soul and use the Valmanway Sword. You can take down all the Bosses in less than five minutes.
Equip yourself in the A set with Dracula's Tunic or Demon Mail, Gungner the Last Spear (recommended due to its reach and does not lose important souls) or Valhmanway Sword, and the Shaman Ring. In the Soul part, equip the Imp Soul in Bullet, the Black Panther in Guardian, and the Mothman in Enchant. In set B, have all the same except for the Chaos ring and the Succubus Bullet Soul. Go to the large falling trail near Lost Village (in front of Yoko's shop there is an entrance where you blow up the ceiling in the fountain). Then, go to the end and you will see an Iron Golem. With set A, use the Imp Soul and the weapon you selected to kill him faster. When you run low on magic, change to set B with X and replenish fast with the Chaos Ring. If you run low on health, use the Succubus Soul to get life from the ghosts on the right and replenish. Go from right to left (from the ghosts' side) with the Phanter soul to go faster. Kill the Iron Golem to get 3,500 experience points each time.
Equip any weapon, any armor, and the Shaman Ring. Equip these Souls: Dead Mate, Black Panther, and Mothman. Then, go to the Wizardry Lab were there are lots of Merman in a room. This is after you pass the big spiked room. Use your Dead Mate Soul to kill the Merman, then leave the room. You can easily gain about 3,000 experience points. Repeat this process as much as desired.
Go to the Lost Village and kill some Axe Armors until you get an axe. Then, go to Yoko's place and upgrade the axe into the Battle Axe. Next, upgrade the Battle Axe into a Bhuj. Then, go to Hammer's shop and sell it for 10,000 gold.
Get the Mimic Soul and go to the Clock Tower. There is a save room with a spike pit next to it at the bottom right corner of the Clock Tower. The Mimic Soul will usually give you 500 gold each time you are hit by the spikes. Whenever you get low on health, go to the save room, heal, and repeat.
If you have a heavy weapon like a great sword, slow attacks can be a problem. To hit an enemy twice quickly, stand very close to them and attack. Then just as it connects, press L to dash backwards. As soon as it stops, you can attack again; if you are still close enough it should hit. This is quicker than just attacking twice normally.
Set Amalaric Sniper Soul as a Bullet Soul, then set Skull Archer as a Guardian Soul. Now when you go to charge the Skull Archer with R, the Amalaric Sniper will automatically activate at the same time and fire alongside. This is a very powerful combo, especially in the early levels. Note: Depending on how long you charge the Skull Archer's soul, it may consume a lot of mana.
In your sets, equip in A: unarmed, any desired armor, and Soul Eater Ring. In the Souls, equip Imp[B], Black Panther[G], and for enchant, you can use anything desired. In set B: use any weapon desired, any desired armor, and Chaos Ring. In Souls, equip Succubus[B], and any other guardian and enchant desired, though Treant[E] is recommended. Then, go to the place in Wizardry Lab where you break the ceiling. Find the fountain in the Lost Village, then fall all the way down, and turn right to find the Iron Golem. Activate Imp[B], and punch the thing very fast and it should die. If you get low on HP or MP, use the Black Panther[G] soul to dash to the room on the right, then switch to set B. The Chaos Ring will replenish your MP and you can use the Succubus[B] soul to get HP from the ghosts. When the process is done, switch back to set A and continue fighting the Golem.
The final two abilities are enemy Souls. These Souls are the Procel and Mudman. The Procel is found in Subterranean Hell and Mudman is found in the Abyss. These Souls allow you to walk through water and stand freely.
There are three secret monsters (Yeti, Mothman, and 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.
In one section of Subterranean Hell there is a see-saw with a boulder sitting on it. In the background are bells hanging on the walls. Hit the flat part of the see-saw with a hammer type weapon. The rewards for ringing the bells are as follows:
Use one of the following methods to get pass the spiked room in Subterranean Hell. The first is to equip these Souls: Puppet Master, Bat Company, and Skeleton Ape. Fly up until you get to a space on the floor with Bat Company. Then, use Puppet Master so you can transfer to the next space. Fly again with Bat Company to the other side. The second method is to equip on your R Souls, Bone Ark. Then just use it from the start of the spiked room and wait for it to carry you the other end.
If you want the best weapons in the game, you must give up some of your Boss Souls. For example, if you want the Claimh Solais, then you must give up the Gergoth Soul.
This trick requires the Succubus Soul and the Cutall weapon. Go to the last save location in the Abyss and do the special attack on the very end of the wall, not near the door. Keep doing the special move until you fall out of the level. It is possible to get back to the save room. If you have a 100% map completion, you will uncover about 56% more if you manage to get back in the save room. Note: If this is done, you will make the final Boss impossible to defeat. After you defeat him, he will just respawn.
Defeat Dario Bossi during the second battle.
Use the Paranoia Soul to enter the mirror during the second battle with Dario Bossi. Defeat Aguni, then return to the other side of the mirror and get the Magic Seal. Then, go to the center of the castle and enter the Boss door without Mina's Talisman.
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 successfully complete the game.
If you have a Witch Soul, let Dmitri copy it. The projectile attack from this Soul is fairly easy to avoid and will make this fight much easier. Additionally, use Une on him and let him copy it. It is the easiest enemy skill to avoid. Also, do not use any R skills (especially the familiars), as he will also copy them and use them along with the bullet skills, giving him two attacks which you must avoid.
To defeat Dmitri in your first encounter with him, use the Axe Armor Soul only, because any other Soul you use will also 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 is defeated. Note: Do not worry if he hits you with the Axe Armor, because it will not do much damage.
Use the Imp Soul; it switches HP damage to MP damage.
