Aura Pull Probability Calculator

Stack skill tree, gem, biome, potion, and finisher multipliers to estimate effective per-roll probability.

Aura Skill tree luck (0 to +25%) Luck Gem bonus (0 to +40%; levels 1 and 4 are sourced) Blacksmith gear luck (0 to +100%) Matching biome bonus Long potion (Fate / Fade +100% / Lucky +50%) Use Destiny finisher (+500,000%)

How this is calculated

P_effective = min(1, P_base × (1 + L_perm) × (1 + L_biome) × (1 + L_potion)). L_perm combines skill tree, gem, and gear.

Selecting a finisher collapses L_potion to a single-roll modifier and disables the time-window logic. See the Luck Setup guide.
