Shield

Right-click toggles a force-field dome. ` + scroll sets its radius (1.5–4).

While it's up:

• All incoming damage is cancelled, explosions ignored (knockback included).
• Mobs and players inside are pushed out; items and XP pass through.
• Harmful projectiles bounce off with a spark instead of being absorbed.

Small shields are egg-shaped and round into a dome as they grow; the surface wobbles (configurable). Turn on Shield durability and it absorbs a set amount before shattering. It clears on death, and other players see your dome's colour and wobble.
