Thing type 304, Automatic Ring, is a Match weapon that can be fired at a rate of 17.5 rings per second. To that effect, it quickly uses up the player's rings, but also increases the chance of hitting a target. Knuckles can fire it at a rate of 35 rings per second. 40 shots are automatically granted upon pickup.
Picking up an Automatic Ring on the map will not allow the player to fire it unless the player has picked up the Automatic Ring Panel previously. However, the ammo granted will be retained (provided the player does not drop it) and will carry over when the player picks up the panel. This weapon will reach its maximum capacity at 400.
Giving an Automatic Ring the Ambush flag will make it float 24 fracunits above the ground. All Automatic Rings that are not already floating above the ground due to Z offsets should have this flag because items that do not float are difficult to collect and look as if they were stuck in the floor. The flag stacks on top of the Thing's regular height, allowing Automatic Rings to be a total of 4119 fracunits above the ground at maximum.
