Damage

In Stardew Valley, damage dealt to monsters is determined by a combination of weapon stats, rings, professions, and good old Luck.

Formula overview

FinalDamage = BaseDamage × CritMultiplier (if crit)
    + Attack (stat) × 3
    × FighterBonus (×1.1 if active)
    × BruteBonus (×1.15 if active)
    × DesperadoBonus (×2 if crit and active)
    → Modified by enchantments
    → Reduced by monster defense

Base damage roll

• A random value is rolled between the weapon’s minDamage and maxDamage.
• Ruby forging increases a weapon's minDamage and maxDamage by 10% per Ruby (up to 3). Three Ruby forges would increase minDamage and maxDamage by 30% total.

Critical Hit Check

• If a crit occurs, the base damage is multiplied by critMultiplier, which is calculated as: critMultiplier = (3 + CritPower / 50) × (1 + CriticalPowerMultiplier)
• CritPower is the total of the Crit. Power stat from Weapons and Jade forging.
• CriticalPowerMultiplier is the effects of buffs: Innate enchantments and Jade Ring

Attack Stat Bonus

• The player’s Attack stat (from food, gear, enchantments) adds: +3 damage per Attack point

Profession Bonuses

• Fighter: +10% damage
• Brute: +15% damage
• These are applied multiplicatively and stack, so if both Fighter and Brute are active, the effective damage increase is 110% × 115% = 127%.

Desperado Profession

• If the hit is a critical strike and the player has the Desperado profession, damage is doubled.

Enchantments

If a weapon is enchanted with Bug Slayer or Crusader and the damaged monster type matches the enchantment effect, damage is increased by 50%.

Monster defense

Monster defense is subtracted from the damage roll. Damage is always at least 1, even after defense reduction.

Critical hit chance

Calculation

Critical hit chance is computed in the following order:

Calculate weapon crit chance

In 1.5, the Aquamarine forging increases weapon critical hit chance by 4.6%. CritChance = Base weapon crit. chance + (4.6% × number of Aquamarine forges)

If weapon type is dagger, CritChance = (CritChance + 0.5%) × 1.12

Apply Aquamarine Ring and innate enchantments

Each aquamarine ring equipped gives a 10% bonus. If the weapon has a "+X Crit. Chance" innate enchantment, then each enchantment level adds a 2% bonus (up to 6% for a level 3 enchantment). (The tooltip displays "+1 Crit. Chance" for a level 1 enchantment.) CritChance = (CritChance × (1 + number of Aquamarine rings × 10% + Innate enchantment level × 2%)

Apply Blessing of Fangs bonus

If the Blessing of Fangs buff from Statue Of Blessings is active, Critical hit chance gets an additive increase of 10%. CritChance = CritChance + 10%

Apply Scout profession

If the player has the Scout Profession, critical hit chance is increased by 50%. CritChance = CritChance × 150%

Apply Luck

Critical hit chance is increased based on the player's Luck. CritChance = LuckLevel * CritChance / 40

Examples

Galaxy Sword build

• Aquamarine forging x3
• Aquamarine ring x2
• Blessing of Fangs
• Scout profession
• 2 Luck

Calculation:

1. Weapon crit chance: 2% + (4.6% × 3 (Aquamarine forging)) = 15.8%
2. Rings & innate enchantment: 15.8% × (1 + 10% × 2 (Aquamarine rings)) = 15.8% × 120% = 19.0%
3. Blessing of Fangs: 19% + 10% = 29%
4. Scout profession: 29% × 150% = 43.4%
5. Luck: 43.4% + 2 (Luck) × 43.4% / 40 = 43.4% + 2.2 = 45.6%

Critical hit damage

Calculation

A critical strike does additional damage to an enemy. A special sound plays when hitting a critical strike, and the damage numbers that pop up show the greater damage amount. A critical strike effectively multiplies the damage roll by a calculated value called CritMultiplier in this article, calculated as follows: CritMultiplier = (3 + Crit. Power (stat) / 50) × (1 + Crit. Power Bonus)

The Desperado Profession also affects the damage dealt by a Critical strike, doubling damage after bonus Attack damage has been added. (Attack stat is otherwise a "flat" bonus which is not increased by Critical strike bonuses.)

Crit. Power (stat) can be found on:

• Weapons
• Jade enchantments: +5 Crit. Power per enchantment

Crit. Power Bonus is increased by:

• Jade Ring: +10% per ring
• Innate enchantments: +50% per enchantment level. A Crit. Power Innate enchantment shows as +25 "Crit. Power" per level, so a "+75 Crit. Power" tooltip represents a level 3 enchantment and thus increases Crit. Power Bonus by 150%.

Example

• A normal attack using the Lava Katana can do 55-64 damage. Assume an attack rolls 60 damage.
• A Lava Katana has 25 Crit. Power, so CritMultiplier = 3 + 25 / 50 = 3.5
• If the Lava Katana was forged with 3 Jades, Crit. Power would be increased by 15, for a total of 40 (though it shows up as +39 ingame due to rounding errors). This means the damage would instead be CritMultiplier = 3 + (25 + 15) / 50 = 3 + 40 / 50 = 3.8.
• With 2 Jade Rings and a +75 Crit. Power (level 3) innate enchantment, Crit. Power Bonus would equal 10% (Jade Ring) x 2 + 150% (Innate enchantment) = 170%, making CritMultiplier = 3.8 × (100% + 170%) = 10.26.
• A base damage roll of 60 damage that was a critical strike with this setup would deal 60 × 10.26 = 615.6 damage.
• The Desperado effectively doubles the damage again (after the Attack stat is applied), so the resulting damage would be 615.6 × 2 = 1231.2.
