Spell Crafting

The most powerful wizards of the realms eventually begin working on the creation of their own spells. The most famous examples of this are the archmages Bigby, Mordenkainen, and Tasha.

Synthesizing your arcane knowledge and power, you strive to create a new spell. To succeed, you must concentrate for 1 hour and meditate on the spell you want to create. Using arcane formulas in your Spellbook, you magically alter one wizard spell you have in your spellbook. You can change the spell’s color, sound, and smell, and you make one of the following modifications to the spell:

Components. Remove one of the spell’s components: Verbal, Somatic, or Material. You can’t remove the Material component of a spell that consumes that component.

Concentration. If the spell requires Concentration, damage can’t break your Concentration on the spell.

Damage Type. If the spell has a damage type, replace it with one of the following types: Acid, Cold, Fire, Lightning, Necrotic, Poison, or Thunder. If the spell has multiple damage types, you can change only one of them.

Range. If the spell has a range of at least 5 feet and doesn’t have a range of Self, increase its range by a number of feet equal to 30 times your Wizard level.

Ritual. If the spell lacks the Ritual tag and has a casting time of at least 10 minutes, give it the Ritual tag.

Targets. If the spell affects one or more creatures and doesn’t have a range of Self, it now affects only your allies or enemies.

You add the altered spell to your spellbook. Once the spell is in your spellbook, it becomes one of your known spells and it gains a name of your choice.
