Mana

**Mana** is a resource that is used to activate spells. Mana can be acquired by matching tile combos on the puzzle board, or by using spells and trinkets. If there is a Sucker in the current room, the amount of mana gained from all sources is reduced by one. There are five colors of mana, which correspond to the five basic tile types:

* White mana is obtained by matching  bone tiles.
* Brown mana is obtained by matching  poop tiles.
* Green mana is obtained by matching  booger tiles.
* Grey mana is obtained by matching  tooth tiles.
* Yellow mana is obtained by matching  pee tiles.

## Mana Costs

Activating a spell consumes mana according to the spell's mana cost. Each spell has a default total mana cost that determines how much mana it will cost in total, however the number of colors of mana required to activate the spell varies.

* Spells with a total mana cost of 1 will always cost 1 mana of 1 color.
* Spells with a total mana cost of 2 will always cost 2 mana of 1 color. The only exception is Converter, which will always cost 1 mana of 2 colors by default.
* Spells with a total mana cost of 4 will either cost 4 mana of 1 color or 2 mana of 2 colors.
* Spells with a total mana cost of 6 will either cost 6 mana of 1 color, 3 mana of 2 colors, or 2 mana of 3 colors.
* Spells with a total mana cost of 10 will either cost 5 mana of 2 colors or 2 mana of 1 color and 4 mana of 2 colors.
* Spells with a total mana cost of 16 will either cost 8 mana of 2 colors or 6 mana of 1 color and 5 mana of 2 colors.
* Spells with a total mana cost of 20 will always cost 7 mana of 2 colors and 6 mana of 1 color.

The table below illustrates this information:

When playing as Bum-bo the Stout, the variety of mana costs is reduced:

Each character's starting spells have preset mana costs, the costs of which sometimes vary from the spells' usual total mana costs. These spells are Attack Fly, Blender Blade, Dead Dove, Puzzle Flick, and Stick.

### Mana Cost Reduction

The mana cost of a spell can sometimes be reduced purchasing a Mana Needle from Jude at the Wooden Nickel, or by using Sleight Of Hand, Golden Tick, or Rainbow Tick. The way the mana cost is lowered depends on which method is used:

* When using a Mana Needle, Rainbow Tick, or Sleight of Hand:
	+ If the spell costs 3 or more mana of any number of colors, **one** of those colors' mana costs is reduced by 1, chosen randomly.
	+ Colors with mana costs of 2 or less are not affected.
* When using Golden Tick:
	+ If the spell costs 3 or more mana of any number of colors, **each** of those colors' mana costs is reduced by 1.
	+ Colors with mana costs of 2 or less are not affected.

### Rerolling A Mana Cost

The mana cost of a spell can be rerolled by purchasing a Shuffle Needle from Jude at the Wooden Nickel, when activating a spell as Bum-bo the Dead, or when using a spell while Bag-O-Trash is in the player's possession. The cost is rerolled by randomly generating a new cost that has the same total mana cost of the default spell; any mana cost reduction is lost when the cost is rerolled. The new cost does not necessarily have the same number of colors of mana as the original spell; it only has to have the same total mana cost.

Converter is a special case. When its cost is rerolled by purchasing a Shuffle Needle, the new cost will always be 2 mana of 1 color. Its cost cannot be rerolled in any other way while it still has its default cost, however its rerolled cost can be rerolled again by any means and will always stay as 2 mana of 1 color.

In certain specific conditions, the mana cost of Attack Fly is rerolled in a special way; specifically, the mana cost will be rerolled such that its new mana cost is always four mana of one color. The special mana cost reroll will happen if the following conditions are met:

* The current character is Bum-bo the Dead.
* The Attack Fly spell that is having its mana cost rerolled is in the first spell slot.
* The mana cost is being rerolled by Bum-bo the Dead's trait or Bag-O-Trash, as opposed to a Shuffle Needle.
