Ars 'n Spells
by otectus
With Ars n Spells installed, Ars spells can be cast from Iron's Spellbooks and the two magic systems share mana and progression.
What it does
The mod bridges Ars Nouveau and Iron's Spells n Spellbooks so that the two systems work as one magic setup rather than two parallel ones. Glyphcraft, spellbooks and mana can be combined through cross-mod features, and an Ars spell cast from an Iron's spellbook runs as a real Iron's spell. Ars Nouveau is required for the core features, while Iron's Spells n Spellbooks is an optional dependency that the mod is built around.
Mana is handled in one of several configurable modes that govern the exchange between the two mana pools. Conversion rates between the systems can be set, and mana regeneration is unit-converted so that percentage-based and flat regeneration do not stack into runaway values. The redundant mana bar is hidden automatically. Ars n Spells is published for Forge and NeoForge, for 1.20.1 and 1.21.1, and it is client and server, so the server and every player need it. The code is not open source; it is released under All rights reserved, though public source code links exist.
Key features
Cross-system gear perks
Armor from one magic system can grant bonuses to the other system's mana pool, depending on the active mode.
Shared progression
Spells cast from one system advance school progression in the other, and the reverse holds as well.
Spell school affinity
School usage is tracked over time with an optional decay, so unused schools fade from the affinity totals.
Spell transcription
A Spell Transcription tablet is crafted and used at a Ritual Brazier to copy a filled spell parchment or focus onto a blank target item.
