You focus your ethereal power into producing a physical instrument to aid you in your witchcraft. You summon one of the following physical effects within range:

• A spellcasting circle. 10 feet in diameter, the circle can be used to cast non-ritual spells as rituals. The entirety of the circle must be on a flat surface. The lines of the circle may take on any appearance you choose, but its colors must be distinct from the surface upon which it has been drawn.
• A cauldron over an unlit fire pit. Once ignited, this cauldron can be used to brew potions with brewing times equal to or less than the duration of this spell.
• A crystal ball. At 2nd level, this can be used as a focus for your Divination feature. Otherwise, it can be used as a spellcasting focus for your witch spells.

If you lose concentration on this spell, all of the physical effects summoned disappear immediately. You can also voluntarily end the spell (no action required).
