Weapon tiers and relic bonuses

Weapon tier	ATK
Ordinary	25
Refined	50
Masterpiece	75
Legendary	100

Relic	Bonus	Condition
Sinister Rune	+40%	Target at full HP
Obsidian Fang	+45%	For 3 seconds after a guard break
Twilight Gem	+30%	For 3 seconds after casting a spell
Witch’s Brew	+20% per empty potion	Counts your empty potions

How the calculator works

Pick the tier of your weapon, tick up to three relics, and set how many empty potions you carry if you use Witch’s Brew. The calculator adds the relic bonuses to your base ATK and shows the burst number. Because the game has 28 weapons across 7 families, the tool uses tier ATK, which is what the guide gives for every family.

Additive or multiplicative?

We could not confirm whether relic bonuses add together or multiply. So the Stacking box lets you choose. With a Legendary weapon and Sinister Rune, Obsidian Fang and Twilight Gem, adding gives +115% for 215 damage, while multiplying gives a larger number. Test one combo in game and pick the mode that matches.

Reading the result honestly

The result assumes every condition is met at the same time: a full-HP target, a fresh guard break and a spell cast within 3 seconds. In real fights those windows overlap only briefly, so treat the number as peak burst, not sustained damage.

Valmanway and doubled attacks

The Valmanway sword is listed at 75 ATK with doubled attacks. Tick the doubled attacks box and pick Masterpiece to see the total per double swing. To unlock it, balance the scales in Paris Streets; track your progress with the Heart Fragment tracker.

The game has 44 relics in total and only four are covered here, so more will be added as verified data appears. For platforms and editions, see our Belmont’s Curse release guide.

Frequently asked questions

How much ATK does each weapon tier have?

Ordinary 25, Refined 50, Masterpiece 75 and Legendary 100.

How many relics can I equip?

Three relic slots can be used at once.

Do relic bonuses stack additively?

It is not confirmed, so the calculator offers both additive and multiplicative modes.

How many weapons are there?

28 weapons across 7 families, according to a weapon locations guide.

Is the result my real DPS?

No. It is peak burst when every relic condition is active at once.

Figures come from community guides published around launch. Patches can change them, so double-check anything important in-game.

What is the Belmont’s Curse relic damage calculator?

Castlevania: Belmont’s Curse has 28 weapons across 7 families and 44 relics, and you can equip 3 relics at once. That is a lot of combinations, and the bonuses depend on conditions such as a full-HP target or a recent guard break. A relic damage calculator adds the bonuses to your weapon’s base attack so you can compare builds quickly.

Players search for it with questions like what the best relic combo is, how much ATK each weapon tier has and whether relic bonuses add or multiply. This page answers the first two with data from community guides and is open about the third, which is not confirmed.

How to use the Belmont’s Curse relic damage calculator

Pick your weapon tier: Ordinary, Refined, Masterpiece or Legendary.
Tick up to three relics.
If you use Witch’s Brew, enter how many empty potions you carry.
Choose the Stacking mode, additive or multiplicative.
Read the burst number, then test one combo in game to see which mode matches.

Belmont’s Curse relic damage calculator worked example

Take a Legendary weapon at 100 ATK with Sinister Rune (+40%), Obsidian Fang (+45%) and Twilight Gem (+30%). In additive mode the bonuses add to +115%, so the burst is 100 plus 115, which is 215 damage. In multiplicative mode the same relics multiply, 1.40 times 1.45 times 1.30, which gives about 2.64 times 100, or roughly 264 damage.

That gap of about 49 points is why the Stacking box exists. We could not confirm which mode the game uses, so test one combination yourself. Remember that the result assumes every condition is met at once, which only happens briefly in real fights, so read it as peak burst, not sustained damage.

Belmont’s Curse relic damage calculator tips and common mistakes

Count Witch’s Brew carefully. It gives +20% per empty potion, so the bonus depends on how many empty potions you carry.
Pick the weapon tier first, because the tier sets the base ATK: 25, 50, 75 or 100.
Use the doubled attacks box for the Valmanway sword, which is listed at 75 ATK with doubled attacks.
Only four of the 44 relics are covered so far, so more will be added when verified data appears.
Check the Heart Fragment tracker if you want to unlock the Valmanway.
