Overview

Spells in Build a Spell are assembled from three kinds of components:

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

Mana cost is the sum of every component, scaled by your Spell Power. Certain combinations of components 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.

Features

• 76 spell components: 7 delivery methods, 47 effects, and 22 modifiers, freely combinable up to 30 components per spell.
• 19 spell combos: special component combinations that unlock unique behavior (Black Hole, Tornado, Void Rift, Fortress, Meteor Strike, Blizzard, summon variants, and more).
• Spell Builder GUI: drag-and-drop component crafting with a grouped palette and live mana-cost feedback.
• Per-spell projectile visuals: choose a projectile's color, shape, and trail particle directly in the builder.
• Arcane Altar: an in-world block for enchanting and unlocking spell components.
• Custom attributes & enchantments: Mana Pool, Mana Regeneration, and Spell Power, with uncapped enchantment scaling(configurable).
• Inter-player portals: dialable, linkable portals for instant travel.
• Deeply configurable: deliveries, effects, modifiers, and roughly 150 individual gameplay numbers are exposed across per-category config files; individual components can be disabled (and become unobtainable) server-side.
• Cross-mod API: a stable public API for other mods to read/modify the attribute system and cast spells.
