Mystic Frontier Dice Calculator

The formula is: (Dice Bonus + Dice 1 + Dice 2 + Dice 3) x Multiplier

Each familiar rolls a die based on its tier:

• Common: d3 (rolls 1-3)
• Rare: d4 (rolls 1-4)
• Epic: d5 (rolls 1-5)
• Unique: d6 (rolls 1-6)
• Legendary: d6 (rolls 1-6)

Potentials and items add dice bonuses (flat values) and multipliers (applied to the total).

Win probability depends on several factors:

• Familiar tiers: Higher tiers roll larger dice
• Dice bonus: Flat additions from potentials and items
• Multiplier: Applied to your total roll
• Target number: The number you need to meet or exceed

The calculator shows both your possible roll range (min to max) and the exact probability of winning.

Dice items obtained during exploration add to your bonuses. There are 4 categories:

• Blessed Dice: Pure dice bonus (+3 to +15)
• Swift Rolling Dice: Pure multiplier (1.2x to 2.0x)
• Sharp Edged Dice: Negative dice (-1) with high multiplier (1.6x to 2.4x)
• Holy Rollers: Positive dice (+1) with multiplier (1.4x to 2.2x)

Items stack during a run. By Stage 5, you may have multiple items boosting your rolls significantly.

Yes! If you've built a deck in the Deck Builder, you can import it directly into the calculator.

This automatically sets your familiar tiers and potential bonuses, saving you time and ensuring accuracy when calculating your win rates.

Target numbers vary by map tier and stage. Higher tier maps have higher targets but better rewards.

Use this calculator to determine which map tiers you can reliably complete with your current deck. A win rate above 80% is generally considered safe for consistent progression.
