Bloodstained: Curse of the Moon/Upgrades

Upgrades
There is an upgrade in every level excluding stage 8 and stage 9. That said, the heart in stage 1 can only be reached in Nightmare mode.


 * The heart increases every character's health bar by two units. It also fully restores the health of whichever character picked it up. These can be found in stages 1 (only in Nightmare mode), 3, and 5.
 * The urn increases the maximum amount of magic by 10 units. It will also give you 10 magic points. These can be found in stages 2 and 4.
 * The gauntlet increases every character's attack power. It can be found in stage 6.
 * The armor increases every character's defense, lowering the amount of damage dealt by enemies. It can be found in stage 7.

Upgrade Locations
You need Gebel to access this heart, so you can only reach it in Nightmare mode. At the end of the very first screen, before you enter the building, there is a staircase on the top right. Switch to Gebel and turn into the bat and fly up there. Continue through this hallway, and at the end you will find a heart. Watch out for the demon about halfway through - I recommend using Miriam's triple daggers or getting up close with Gebel.
 * Stage 01 - Moonlight Temptation - Nightmare Mode Only

This is along the mandatory route so there's no way to miss it, though you need Miriam alive to access it. Near the end of the stage you'll descend a staircase into an icy hallway. Continue down this hallway and soon you'll see the urn underneath an elevated platform. It's blocked by a wall, but you can destroy the block in the lower left corner. Do so and then slide under with Miriam to grab it. If you're on nightmare mode, you can also use Gebel as the bat to get through this gap.
 * Stage 02 - Frigid Hell

Once again, this one is in a mandatory route and impossible to miss. Near the end of the stage, you'll descend into a dark room with many staircases heading down. The heart will be just to your left as you enter, but the gap to get to it is small. Either slide under with Miriam or fly through with Gebel's bat transformation. Even if you have Zangetsu's double jump, you can't reach this one with him, so don't try.
 * Stage 03 - The Brilliant Void

Relatively late in the stage, you'll take a staircase up onto a roof, and you'll see the urn right above you. Use Miriam's high jump to ascend the wall to your left, then jump up onto the floating platform and slide through to receive your prize. Alternatively, fly up with Gebel's bat transformation. As a bonus, drop straight down and attack the wall directly to your right to find a hidden health restore - nice.
 * Stage 04 - Blasphemy unto Heaven

You'll see this one partway through the stage, floating on a platform guarded by a wall dragon. If you have Gebel, just transform into the bat and fly up there and grab your heart while dodging the dragon's fireballs. Alternatively, you can use Alfred's ice magic at the right time to freeze the dragon and climb it up like a staircase, but this requires great timing.
 * Stage 05 - Sunder the Night

Stage 06 - Tragedy of Slaughter You'll see the gauntlet on the second screen of the stage, below you. To reach it, you can slide under the adjacent platform with Miriam, fly down with Gebel's bat transformation, or freeze the lava with Alfred's ice magic and jump down. If you have Zangetsu's double jump, you can drop straight down and jump onto the platform at the last second.

Stage 07 - Defiler of Taboos You'll see the armor on the third screen of the stage, after the room with all the elevators. It's impossible to miss, being just to your right on an elevated platform. Jump up there with Miriam or fly up with Gebel's bat. If you have Zangetsu's double jump, that works too.

There are no upgrades in stage 8 nor the Nightmare mode exclusive stage 9.
