Description:

Arcane Binding Grimoire: A magical book held in the off-hand that displays a mana UI and contains multiple pages of spells (types ranked by mana cost). Right-click with the Grimoire in the off-hand to open a central spell menu. Spells are unlocked/purchased using mob drops from the player's inventory (low-tier spells use common drops; higher tiers require rarer drops). Bind spells to hotbar slots with: /bind spell {Spell Name} {Slot 1-9}. Once bound, spells remain active while the Grimoire is anywhere in the player's inventory. To cast bound hotbar spells the player must equip a staff in the off-hand; cycling hotbar slots selects spells (default 1 second swap cooldown). Grimoires are craftable or obtainable via trades with the Arcanist villager, which spawns in its own tower.
