What Lucky does

Current rules

Read the words immediately before Lucky. If Hit Damage is Lucky, roll the eligible Hit damage range twice and keep the higher damage. If Critical Hit chance is Lucky, make the success roll twice and succeed if either roll succeeds. Lucky damage does not make Accuracy, Critical Hit chance, or ailment damage Lucky unless they are named separately.

Roll twice, keep the better result: Lucky repeats the affected roll once and uses the result that is better for the entity receiving the Lucky modifier.
The named roll controls the scope: Hit Damage is Lucky affects the Hit's damage range. Critical Hit chance is Lucky affects whether a Hit is critical. Chance to Block Damage is Lucky affects the Block roll. These are separate rolls.
Binary chance formula: For an original success chance p, a Lucky binary roll succeeds with probability 2p minus p squared. For example, 40% Critical Hit chance becomes a 64% effective chance when that Critical Hit chance is Lucky.
Damage uses the eligible final range: Wording that makes Damage or Damage with Hits Lucky rolls within the eligible damage range after applicable increased and more modifiers. It does not reroll only the weapon's base damage.
Lucky Hit damage does not reroll ailment damage: Damaging ailments roll their damage independently. Making the Hit damage Lucky does not make the resulting Ignite, Bleeding, or Poison damage roll Lucky unless the ailment damage is explicitly affected.
A chance to be Lucky is conditional: A modifier such as 30% chance for Spell Damage with Critical Hits to be Lucky first checks whether the eligible damage roll receives Luck. It does not add 30% Critical Hit chance and does not make every spell Hit Lucky.
Lucky and Unlucky cancel for the same roll: If the same stat or mechanic is both Lucky and Unlucky, the two modifiers cancel and that roll is made normally. Different named rolls can still be Lucky and Unlucky at the same time.

4 rules

Lucky does not mean every random event performed by the character is rolled twice.
Multiple sources of Lucky for the same roll do not keep adding rerolls.
A partial chance for a roll to be Lucky is not the same as increasing the original success chance by that percentage.
Lucky damage affects only the damage types and delivery method named by the modifier.

mechanicUnlucky

An Unlucky value is rolled twice and the worse result is used. The modifier affects only the named roll, such as enemy Hit damage, Physical Hit damage, Lightning Hit damage, Critical Hit chance, or Evasion chance.

mechanicDamage

Damage is classified on three independent axes: source, delivery, and type. A component can come from an Attack, Spell, Thorns, or another source; deal a Hit or damage over time; and deal Physical, Fire, Cold, Lightning, or Chaos damage.

mechanicHit

A Hit is an instantaneous damage event. Any damage that is not damage over time is Hit damage, whether it comes from an Attack, a Spell, Thorns, or another effect.

mechanicCritical Hit

Critical Hits deal +100% extra damage (i.e. twice as much damage) by default. Critical Damage Bonuses can further modify this value.

mechanicBlock

Block prevents the damage of a blockable Hit. Passive Block rolls the character's Block chance for each eligible Hit, while active Block from a raised shield guarantees a block from the protected direction under that skill's rules.

mechanicDeflect

Deflection Rating gives a chance to Deflect damage from Hits. A normal Deflection prevents 40% of the Hit damage, while the chance depends on your Deflection Rating and the attacker's Accuracy Rating.

You are Surrounded when at least five enemies are within 3 metres of your character. Surrounded is a condition, not a Buff: it has no duration, does not stack, and grants nothing by itself. Items, passive skills, and Support Gems check whether the condition is currently true and apply their own listed effects while it is.

mechanicParried

Enemies you Parry with a Buckler take more Attack Damage and cannot Evade Attacks for a duration.

mechanicThorns

Thorns is Hit damage dealt as a separate hit. By default, a character with Thorns retaliates when an enemy hits them with a Melee Attack.

mechanicArmour Break

Armour Break lowers a target's Armour by a specified amount. Reaching 0 applies Fully Broken Armour, which removes the target's Armour benefit and has additional effects against monsters.
