Dolphin
Increases your movement speed in water, making swimming much faster. Useful for water-heavy maps.
Horizontal speed
How fast you move laterally while swimming.
Range: 1-8.
Vertical speed
How fast you ascend or descend while swimming.
Range: 1-8.
Buoyant
Automatically rise toward the surface while swimming forward.
Disable while using
Pause Dolphin when you right-click (eating, blocking, etc.) while in water.
Disable vertical while moving
Only apply vertical speed when you're not pressing a movement key. Prevents fighting between horizontal and vertical motion when strafing underwater.
Forward only
Only apply the speed boost when pressing forward, not while strafing.
