RunelessRPG is a mana system for Spell Engine on Minecraft 1.21.1 (NeoForge). Spells, class skills and weapon skills cost mana instead of runes. Every player has a mana pool that regenerates over time, gear and potions make it bigger or faster, and a mana display sits next to the hotbar.
It is built for pack developers: base values, costs per spell tier, categories, multipliers and the mana mode are config options; which spell belongs to which category is a spell tag; single spells can get their own cost from a datapack. Nothing is tied to one pack.

- Mana instead of runes: rune costs of Spell Engine spells are replaced by mana. Runes are never consumed, arrows stay as they are. See Spell costs.
- Six attributes: Max Mana, Mana Regeneration, Mana Cost, Overcharge, Mana Leech and Spell Mana Leech, usable on any gear. See Mana and attributes.
- Cost by tier: a table of base costs per spell tier (4, 5, 7, 10, 14, 18) and a multiplier per category (spells, class skills, weapon skills, item abilities).
- Channeled spells pay while they channel: stopping early is cheaper, interrupting still sets the cooldown.
- Overcharge and leech: spend more mana for more damage and healing; win mana back with weapon and spell hits. See Overcharge and leech.
- Mana HUD with six styles, docking at Miki's Fantasy HUD, a layout editor and its own mana number. See Mana HUD.
- Seven enchantments and mana potions (Potion of Mana, Magical Stability, Borrowed Power). See Enchantments and Potions.
- Apotheosis affixes for all six attributes when Apotheosis is installed. See Apotheosis affixes.
- Commands, API and events for packs and other mods. See Commands and API and events.
- Install NeoForge
21.1for Minecraft1.21.1and Spell Engine1.10.0or newer (it brings Spell Power, Cloth Config and playerAnimator with it). - Put the RunelessRPG jar into the
modsfolder of the server and every client. - Play. Every player starts with 20 mana and 0.5 mana per second. Spells that cost runes now cost mana; the cost is shown in the spell tooltip.
Without any optional mod, the mana bar sits beside the hotbar, every Spell Engine spell that costs runes costs mana instead, and the class skills and weapon skills listed in the bundled tags cost mana as soon as their mods are installed. Enchantments and potions are always there. Affixes only exist with Apotheosis; the bar docks at Miki's Fantasy HUD only when that is installed.
