Odds by Forge

The Forge level caps the tier and unlocks effects and 2-attribute gems.

Forge cap: Tier II. Anything rolled above it comes out at the cap.

Forge level: Forge 0–3
Guarantee: Tier II guaranteed within 80 openings in a row without Tier IV or higher.
Effect: Rolled among 3, all with the same chance: Attack, Defense and HP.

Forge cap: Tier III. Anything rolled above it comes out at the cap.

Forge level: Forge 4–5
Guarantee: Tier III guaranteed within 80 openings in a row without Tier IV or higher.
Effect: Rolled among 6, all with the same chance: Attack, Defense, HP, Crit Chance, Dodge and March Speed.

Forge cap: Tier IV. Anything rolled above it comes out at the cap.

Forge level: Forge 6–7
Guarantee: Tier IV guaranteed within 80 openings in a row without Tier IV or higher.
Effect: Rolled among 6, all with the same chance: Attack, Defense, HP, Crit Chance, Dodge and March Speed.
2 attributes: Tier III 8% · Tier IV 12% — not when the first effect is March Speed.

Forge cap: Tier V. Anything rolled above it comes out at the cap.

Forge level: Forge 8–10
Guarantee: Tier IV guaranteed within 80 openings in a row without Tier IV or higher.
Effect: Rolled among 13, all with the same chance: Attack, Defense, HP, Crit Chance, Dodge, March Speed, Penetration, Lifesteal, Precision, Block, Damage Reduction, Crit Damage and Resource Gain.
2 attributes: Tier III 8% · Tier IV 12% · Tier V 18% — not when the first effect is March Speed and Resource Gain.

Rising luck: After 60 openings in a row without Tier IV or higher, the Tier IV chance rises with every opening up to the guarantee (above the Forge cap, it comes out at the cap).
Meter: Resets when Tier IV or higher drops, or when the guarantee pays out.
Bonus: 0.5% per opening for +1 Lineage Crest II, on top of the gem (never instead of it), within the weekly Legacy cap.
