Stamina

The stamina bar replaces the experience bar. Most actions cost stamina, with the exception of a few things like sprinting, jumping, and crafting.

Doing stamina-costing actions above/below sea level will cost increasing amounts of stamina and once the stamina bar runs out, actions eat into your saturation and then your hunger bar instead.

Stamina is effectively a buffer for your hunger bar, and waiting for it to regenerate can be substituted by using your hunger bar and restoring it with food, making food a valuable resource for performing many actions in a short period of time.

Players have a maximum stamina of 100, regenerating 0.5 stamina a second. There is no way to increase this regeneration.

Some examples of common stamina costs

Action	Cost
Placing Cobblestone	1
Breaking Iron Ore	10
Hitting an entity	10
Filling a Water Bucket	5
Emptying a Water Bucket	5
Dropping a Water Bucket	20
Picking up a Water Bucket	5
Jumping with a Water Bucket	10
Shooting a Bow	10
Loading a Crossbow	20
Rowing a Boat	0.05 per tick

Some blocks have greatly increased stamina costs to place and mine. These blocks are intended for use in defensive structures, allowing players to prevent their structures from being easily attacked/griefed:

Blocks	Break Cost	Place Cost
Obsidian	50	20
Bricks	50	20
Mud bricks	50	20
Smooth stone	50	20
