Description: Small server-side mod that adds config options Iron's doesn't have. Lives in its own toml so it doesn't touch Iron's serverconfig.
- mana regen rate
- starting mana
- cooldown reduction bonus
- cast time reduction bonus
- dimension casting blacklist
- global spell level cap
- inscription blacklist
- full mana regen disable toggle
Why: NightfallCraft is built around Epic Fight and boss progression. Iron's casters can blow past that curve fast since mana regen rate and starting mana aren't actually configurable on Iron's side. The spell level cap lets you gate high tier spells behind progression and the dimension blacklist lets you turn off casting in specific boss arenas. Works alongside Iron's per-spell jsons if you want fine tuning on top.
Other relevant info: 1.20.1 Forge. Needs Iron's 3.0.0+. Soft dep so it does nothing if Iron's isn't there. No mixins. No ATs. Server side only. MIT.
