Spell Creation

Drawing a blood circle

Take damage to receive the Bleeding effect. Any positive damage works; right-clicking with a Dagger is the controlled option.
While Bleeding is active, face a suitable floor with free space and press M, the default Draw Mahoujin key.
A blank blood circle is placed on the floor in front of you. Drawing the first circle also unlocks the mana display.

Ordinary damage gives you five seconds to draw. The Dagger deals 2 damage and gives you fifteen seconds. Key assignments can be changed in Minecraft's Controls menu.

Adding catalysts

Right-click the blank circle with each of the three required powdered catalysts. The circle changes into the matching spell after the third valid catalyst is consumed.

Right-click a new blank circle with an empty hand to repeat your previous catalyst recipe. The required powders must be in your inventory or supported carried storage. Recipes made on Spell Cloth also consume one Spell Cloth.

The spell index shows each catalyst recipe and whether it uses a blood circle, Spell Cloth, or both.

Active Circles

Some spells remain at their location and operate from there. Its spell page explains activation, mana use, range, ownership, and removal.

Right-click with an empty hand to toggle a Boundary circle created on the floor.

Making a scroll

Spell Cloth

White Wool

Dagger

Result: 4 Spell Cloth

Place one Spell Cloth on a suitable floor.
Take damage and draw the blood circle directly on the Spell Cloth.
Apply the spell's three powdered catalysts.
Right-click the completed circle with an empty hand to receive the scroll. The circle and its Spell Cloth are removed.

Individual spell pages explain how their scroll is aimed or activated. Successfully used scrolls are normally consumed in Survival mode.

If a circle does not form

Confirm that the Bleeding effect is still active and Draw Mahoujin is not conflicting with another control.
Face a solid surface with enough free space for the circle. Servers can restrict circles to solid blocks.
Check that exactly three correct powders were used. Repeated catalysts require multiple copies.
Place Spell Cloth first when the spell is marked Scroll.
A server may block a spell with SPELL_BLACKLIST or require a GameStage.
Use /showmahou if the mana display was hidden. The command is available to ordinary players.
