Enchantment/Anvil Cost

Work out the total XP-level cost of an anvil combine, including the prior-work penalty from each item's own history.

Anvil Cost

Enchantment/Repair Cost (levels, before penalty)

The base level cost of the enchantment(s) or repair material being applied - this varies per enchantment and isn't itself calculated here.

Target Item - Prior Anvil Uses

Sacrifice Item - Prior Anvil Uses

Each time an item is combined or renamed in an anvil, its "times used" counter goes up, doubling that item's penalty on its next anvil use.
