Surpassing | PoE2 Mechanic

What Surpassing does

Current rules

Divide the final Surpassing chance by 100%. The whole-number part is the guaranteed number of occurrences and the remainder is the chance for one additional occurrence. A 215% Surpassing chance therefore occurs twice and has a 15% chance to occur a third time. Ordinary chance wording still caps at 100% unless it explicitly says Surpassing.

Each 100% guarantees one occurrence: A Surpassing chance of 100% guarantees one occurrence, 200% guarantees two, and 300% guarantees three.
The remainder rolls once more: After guaranteed occurrences are counted, the percentage left over is rolled for one additional occurrence. At 275%, two are guaranteed and the third has a 75% chance.
Only explicit Surpassing wording exceeds 100%: A normal chance-based stat does not gain repeated outcomes above 100%. The modifier must state that its chance is Surpassing.
Add matching chances before splitting the total: Matching Surpassing chances for the same event combine into the final chance. The guaranteed occurrences and remainder are then calculated from that total.
The repeated result depends on the event: For an additional Arrow, each guaranteed occurrence adds another Arrow. For a stack or reward chance, each occurrence grants that stated result unless the source also gives a maximum.

mechanicProjectile

A Projectile is a moving entity created by an Attack or Spell. Projectile describes delivery, not the source type or damage type, so the Projectile can still be an Attack or Spell and can deal any supported damage type.

mechanicCommand

Command Skills let the player order a permanent Minion to perform a specific action. The player issues the command, but the corresponding Minion performs the commanded Skill.

mechanicMonster Power

Monster Power is an underlying number that represents how strong and dangerous a monster is. Skills, Warcries, items, Glory generation and charge recovery can count or scale from that number.

mechanicRarity

Rarity describes an item's structural state, a monster's category, or the strength of a loot upgrade. These are related systems, but they are not the same stat.
