Limit Break

Limit Break is a sub-skill shared by mcMMO's combat skills. It adds flat bonus damage that grows as you rank it up, but is reduced by how good your target's armor is, so it closes the gap against heavily-armored opponents without one-shotting unarmored ones.

By default, Limit Break only works in PvP (player versus player).

Which skills have it

Eight combat skills each have their own Limit Break sub-skill, all capped at rank 10:

Swords · Axes · Unarmed · Maces · Spears · Tridents · Archery · Crossbows

Each levels with its parent skill: they share the parent's XP and ranks unlock at the parent's level thresholds (see Skill Ranks).

How the bonus damage works

The base bonus is simply your current rank in that skill's Limit Break (1 extra damage per rank, up to +10 at rank 10). That raw bonus is then scaled down by the target's armor quality:

rawBonus   = rank in <skill> Limit Break        (1–10)
finalBonus = floor( rawBonus × armorQualityMultiplier )

The result is also multiplied by your attack-strength scale. Spamming attacks before the 1.9+ attack cooldown recharges weakens the bonus, like all mcMMO combat damage. See Attack Cooldown.

Example: rank 10 Swords Limit Break vs. an opponent at armor quality 6:

rawBonus   = 10
finalBonus = floor(10 × 0.50) = 5 bonus damage  (before attack-strength scaling)

PvE (mobs)

Against mobs, Limit Break is off by default. Mobs are treated as armor quality 1000 (the full ×1.00 tier), so if you enable it, the bonus applies at full strength against them. Turn it on in advanced.yml:

Skills:
    General:
        LimitBreak:
            AllowPVE: false   # set true to let Limit Break boost damage vs mobs too

Permissions

Limit Break uses each skill's standard sub-skill permission. The node repeats the skill name, e.g. mcmmo.ability.swords.swordslimitbreak, mcmmo.ability.axes.axeslimitbreak, mcmmo.ability.archery.archerylimitbreak, etc. These are part of the default skill grants; see Permissions.
