Angel Belt is a Vintage Story mod by Buggi. Angel Belt adds a wearable flight tool: equip it in the belt slot, press R, and adjust movement speed and axis controls while airborne.

Why this mod is worth installing
Useful for builders who want to work above ground without scaffolding, and for explorers who need controlled aerial movement. Server owners can optionally enable charge consumption for flight.
What Angel Belt adds
Angel Belt is worn in the belt slot and toggles flight with the R key. When flight is active, you can move freely through the air, making tall construction and hard-to-reach locations easier to access.
The controls include adjustable movement speed, fine speed changes, axis locking, and a command to restore the default modifiers. The selected settings remain available after disabling and reactivating the belt.
The optional charge system is controlled by the server configuration rather than by the item itself. Flight stops when the available charge is depleted, and higher speed consumes charge much faster because the cost increases with the square of the speed multiplier.
