Spawner XP Optimizer

Model a spawner farm before you dig it out. Mob rate, XP per hour and how many levels an hour of AFK actually gets you.

Output

Mobs per hour

260

XP per hour

2,600

Levels from zero

One hour of AFK

Mending repair

5,200 durability

2 durability per XP point

The single biggest gain is clearing the full 9x9x3 spawn volume centred on the spawner and standing far enough away that mobs never despawn but the spawner still ticks. Looting III does not increase XP, only drops.
