miaoModifiesIronspellsArtifacts
by MKUXQQQ
miaoModifiesIronspellsArtifacts is a Forge and NeoForge add-on for Iron's Spells 'n Spellbooks that lets server owners tune spell parameters with more precision.
What it does
The add-on changes core spell parameters of Iron's Spells 'n Spellbooks: cast time, spell power multipliers, cooldowns and mana cost. Values can be set at tick-level or decimal precision, so a server can move a spell's balance in small steps. Single-player worlds can use the same settings to build a custom difficulty, and map makers can use them for special gameplay designs.
Changes are made through a dedicated configuration tool for the Minecraft Cat Modifier family, so the settings sit in a separate file rather than in the base mod's options. Balance adjustments made on the server apply to every player who joins, which makes the add-on useful for shared worlds that need one consistent set of spell values.
Files exist for 1.20.1 and 1.21.1, with Forge builds and NeoForge builds for 1.21.1. The mod is released under the Apache License 2.0, which is not an open source license, and it runs on client and server: the server and every player need it, and the add-on depends on Iron's Spells 'n Spellbooks being present.
Key features
Cast time adjustment
Spell casting duration can be set at tick-level precision, so each cast can be made slower or faster by a small amount.
Spell power multipliers
Damage multipliers for each spell accept decimal values, allowing fine adjustments to how hard a spell hits.
Custom cooldowns
Recovery time for each spell can be set to a chosen value, which changes how often a player can cast it.
Mana cost tuning
Mana consumption for each spell can be fine-tuned to shape the pace of combat and resource use.
Custom map mechanics
The same parameters can be combined into special gameplay designs for maps built around spells.
