Build a Spell

A component-based spell creation system for NeoForge: design your own spells from delivery methods, effects, and modifiers, unlock them through a rune-and-essence progression, and discover powerful multi-component combos.

  • Spell crafters: browse the Spell Components Reference for every delivery, effect, modifier, and combo.
  • Server admins: see Configuration for the per-category config files and what you can tune or disable.
  • Mod developers: the Cross-Mod API shows how to read and modify mana, spell power, and casting from another mod.

How spells work

Spells are assembled from three kinds of components:

  • Delivery method: how the spell is cast (self, line of sight, projectile, homing projectile, touch, a timed ground rune, or a proximity trap).
  • Effects: what the spell does (damage, status effects, terrain manipulation, summons, utility).
  • Modifiers: how the effects behave (more power, larger area, longer duration, chaining, piercing, and shape modifiers).

Mana cost is the sum of every component, discounted a little by a held wand, with repeats priced higher each time: a second copy of an effect, or a second stack of a modifier on the same effect, costs more than the first. Double and Echo are the exception to the sum: each is charged a share of what the rest of the spell costs, because each one re-scales everything the spell does rather than adding a fixed amount to it. Certain combinations form combos that override their individual behavior to produce a single, more powerful spell: black holes, tornadoes, Void Rifts (dialable, linkable portals), summon swarms, and more.
