Combat

How attack damage, armor and critical hits are calculated.

Name	Summary
Armor and toughness	Each armor point blocks 4% of a hit, up to 80% at 20 points, and strong hits count fewer armor points unless the wearer has armor toughness.
Armor points	Only whole armor points count: a fractional armor value is rounded down before damage is reduced.
Attack charge	After each swing a weapon recharges over 20 ÷ attack speed game ticks, and attacks made before it is full deal less damage.
Attack damage	A melee hit deals between 20% and 100% of the weapon's attack damage, depending on attack charge.
Critical hits	An attack made while falling, at more than 90% attack charge, deals 1.5 times the weapon's damage.
Protection	Protection enchantments block 4% of matching damage per protection point, up to 80% at 20 points.
Sweeping attacks	A sword attack sweeps when it is made at more than 90% attack charge while standing on the ground, and is neither a critical hit nor a sprint-knockback hit.
Sweeping damage	A sweeping attack deals 1 damage to each mob next to the target, plus a share of the main hit's damage when the sword has Sweeping Edge.
