How to Use the The Forge Calculator: Weapon Stats & Damage Output

1Enter your base weapon damage before upgrades.
2Set the weapon enhancement level (+1 through +15).
3Adjust your critical strike chance (%) and critical damage multiplier (%).
4Review your calculated normal hit, critical strike damage, and armor reduction percentage.

Formula & How It Works

RPG Weapon Enhancement & Armor Scaling

Damage = Base × (1 + Level × 0.08) × StatMult × (100 / (100 + Armor))

Applies enhancement progression and hyperbolic armor reduction curves.

Worked Examples

Enhancing a 150 Damage Sword to +7

Input: Base: 150, Level: 7, StatMult: 120%, Armor: 60

Explanation: Weapon gains +56% damage from level 7, scaled by stats, then mitigated 37.5% by enemy armor.

Result: Normal Hit: 175, Critical Hit: 350, Expected DPS: 219

Frequently Asked Questions

How does enemy armor reduction work?▼

Armor uses an effective health formula: Damage = Raw × (100 / (100 + Armor)). 100 armor reduces incoming damage by exactly 50%.

What is expected average damage (DPS)?▼

Expected damage weighs normal hits against critical hits based on your critical strike probability: Normal × (1 - Crit) + CritHit × Crit.

What is the optimal balance between Crit Chance and Crit Damage?▼

Maintaining roughly a 1:2 ratio (e.g. 50% Crit Chance with 200% Crit Damage) yields mathematical efficiency.

Does weapon enhancement scale base damage or total damage?▼

Enhancements scale the base weapon damage, which is then multiplied by your character's primary attribute bonuses.

⚠️ Common Pitfalls to Avoid

•Investing purely in base damage while neglecting critical chance and critical damage synergy.
•Ignoring diminishing returns on high armor values against end-game bosses.
