Spells are equipped in the two spell slots, located on the right of the screen. They are bound to the Up+Right and Down+Right keys.
Upon using a spell, you cannot use it again until you have killed the required number of enemies to refresh the spell. The number of kills remaining is displayed over the spell's slot. Killing enemies with the spell count towards the number of kills. Enemies that stand on spike traps or get killed via other enemies also count.
Having a Ring of Mana will allow the player to cast a more powerful version of the spell (equivalent of the scroll version) and reduces the cooldown time by 4 times. The Ring of Wonder will reduce cooldowns, but not increase power.
Using a spell during its cooldown will hurt the player but still cast the spell. This is known as "Blood Magic". Using blood magic resets the cooldown counter. Blood magic used after taking the stairs does not damage the player, although the cooldown counter is still reset, which can be used for a free half heart from the heal spell .
|Spell||Range||Refresh||Blood magic cost||Effect|
| ||Horizontally up to the first wall in both directions.||10 enemies|| || Flames shoot horizontally from both hands of the player, dealing 3 base damage to all enemies it contacts. Turns ice into water and water into normal floor if the spell passes over the tile.
Does a base of 8 damage if the Ring of Mana is equipped.
| ||An approximate circle with 5 tile radius from the player.||15 enemies|| || Freezes monsters in a circle with 5 tile radius, making them unable to move or attack. The effect lasts for 8 beats, and the effect wears off after player action on the last beat, so the frozen monsters miss a total of 8 beats. Inside the radius, turns water and tar into ice, and removes hot coals.
If the Ring of Mana is equipped, the spell has an infinite radius and lasts 16 beats.
Many monsters that ordinarily can't be damaged or can't be attacked become vulnerable while frozen: tar monsters, blademasters, trap chests, trap walls, trap cauldrons. The following monsters remain invulnerable: rolling armadillos, shelled beetles, buried moles.
Freezing effects stack: when freezing a monster that is already frozen, the original freeze duration is extended by the duration of the new effect.
| ||The player.||15 enemies|| || Heals the player for 0.5 health.|
When cast with blood magic, the net effect is to lose 0.5 heart, and the heal is applied before the blood magic cost. Thus if the player is at 1 heart, she will be reduced to 0.5 heart without dying, and if the player is at full life, she will lose a full 1 heart.
If the Ring of Mana is equipped, it heals the player for 1 health.
| ||The tile the player is standing on.||25 enemies|| || The player summons and places a bomb. The effect is the same as using a consumable bomb: after 3 beats, it explodes in a 3x3 area, damaging monsters and destroying walls.
If the Ring of Mana is equipped, the bomb deals 999 damage.
| ||The player.||20 enemies|| || Makes the player invincible for 8 beats. If the Ring of Mana is equipped, the spell lasts for 20 beats.
The player still takes damage if purchasing from the Blood Shop.
| ||3x3 area centered on the player.||20 enemies|| || Transforms items on the ground in a 3x3 radius (but not in inventory) into other random items.
Does not affect gold.
Shop items don't change prices.
Will not transmute bombs placed by player (including those from the Bomb Spell).
If the Ring of Mana is equipped, the spell will transmute all items on the ground within the current level.
After approximately 320 items have been transmuted, any further items transmuted will be destroyed instead.
| ||3x3 area centered on the player.||10 enemies|| || All empty tiles surrounding the player is filled with dirt walls.
Monsters, crates, barrels and Teh Urn are knocked away from the player unless there is something in the way. Otherwise, it is instantly destroyed. This is especially useful for quickly killing bosses.
Items and gold that are trapped in dirt tiles can be collected by digging the tile.
If the Ring of Mana is equipped, the spell will fill a 5x5 area centered on the player with dirt walls.
| ||5x5 diagonal cross centered on the player||10 enemies|| || A 5x5 diagonal cross shoots from the player, dealing 5 damage to all enemies it contacts.
If the Ring of Mana is equipped, the spell deals 10 damage.
| ||The player.||No recharge.||N/A|| Transforms the player into a bat. When in bat form, the player becomes immune to all traps and floor hazards, is able to see all monsters and NPCs, and gains a dagger-range attack that deals 4 normal damage and replenishes the player 0.5 health after 5 kills. Any carried items cannot be used while in bat form. Spells can still be cast.
The player takes 0.5 heart of damage when transforming back into human form.
