SpellActionbar

Spell Actionbar adds a dedicated spell bar for Iron's Spells 'n Spellbooks. Equip scrolls, cast with Iron's quick-cast keys, and see icons, cooldowns, mana, and keybind labels above your hotbar.

How it works

• Open the equip screen with the Spell Actionbar key (default `)
• Place Iron's scrolls into free actionbar slots
• Cast with Iron's quick-cast keybinds — the HUD shows the bound key on each slot
• Scrolls are not consumed when casting from the bar

Spellbooks & slot count

• With no Curios spellbook equipped, the bar has 3 slots
• An equipped spellbook sets the bar size to that book's max spell capacity
• Packed book spells lock into the leading slots — they cast from the book and cannot be moved in the equip screen
• Remaining slots are yours for player scrolls
• If the book shrinks or locks over a scroll slot, those scrolls are returned to your inventory (dropped if full)

HUD

• Spell icons, cooldown overlays, and affordability tinting
• Compact keybind labels (e.g. Q, s1, cR)
• Mana bar styled for this actionbar
• Iron's native spell bar and mana overlay are hidden so they don't stack

For pack makers & addons

• Other mods can open a custom equip UI via SpellActionbarMenuOpeners
• Cast gating helpers (ActionbarCastGate) for addons such as Specs: Iron's Spells 'n Spellbooks Addon
• HUD offset preview/persist APIs for companion HUD editors

Requirements

• Minecraft 1.21.1 / NeoForge
• Iron's Spells 'n Spellbooks + Iron's Lib
• Curios (pulled in by Iron's)
