Settings

Three places, by scope.

Client config — Mod Menu / the mod-list config button. Per-player display and feel: HUD toggles, billboard scale/time, dome and beam defaults, shield colour/wobble, structure-preview colours, block-UI rows, Commands: max boxes, beam grab pulls entity to you, per-type projectile speeds, ride-particle trail, ability-number layout. Cloth Config gives a nicer version of this screen if installed.

Server settings — /commandstaff settings (op only). One screen, three tabs:

• Settings — server-wide rules: shield durability + max damage, max controlled projectiles, projectile collect speed, defense-wall max distance, abilities-while-riding, control: consume arrows, quick-choose toggles.
• Abilities / Commands — a node graph to disable any ability, mode, sub-mode or command server-wide. Click to select (Shift = range, Ctrl = toggle one), then Enable / Disable. Disabled commands show a 🔒 in the picker. Saved per-world.

In-game — most per-ability values are adjustable on the fly with ` + scroll and Left Alt, no menu needed.
