Wizardry Lab (3)

Drop into the water to find a Homunculus. You can kill them or let them chase you until they suffocate.

Head left, and after passing the second Homunculus, jump to the top of the water to grab a Serenity Robe.

Drop back down, continue left, kill another Homunculus, jump to the top, and go left.

In the next area, deal with two Larvae. Drop to the bottom and head left.

Drop to the bottom and collect the Super Potion after defeating a Homunculus.

Jump back up and continue left. At the far left is a pit leading to a Bloody Stud.

Jump up to the top and head left.

Proceed through the room that feels like nothing happens.

Skip the next funky room for now. Drop down, take out Mermen, and head left.

In the room populated by Killer Fish and Homunculi, head to the far upper left.

If your monetary supply ends in 666, enter the golden door with 666 on it.

Grab the Gold Ring inside the door. Equip this immediately.

Backtrack to the junction room with a massive amount of Ghosts (it's right after the weird room with the candles).

In the room with infinite Ghosts and invisible platforms, use the Ghosts as boosts by jump-kicking them to elevate Soma. The Armor Lord soul is recommended for defense.

Navigate the invisible platforms by double-jumping off Ghosts. Go left when you can't jump higher.

Land on a platform, double jump up, right, and left around a platform, then double jump to the platform above.

From there, double jump across to the upper right platform and jump-kick Ghosts to reach the upper area. Use the platforms according to the map if you fall.

Go left at the top.

In the room with an Iron Golem, use Puppet Master to get behind it. Hit it with a weapon or soul that hits multiple times, like the Kaiser Knuckle or Une soul, as you will only deal 1 HP of damage per hit.
