Effective Stat Prediction (DPS & EHP)

Reject fake stats. We calculate true combat value by factoring in attack speed, crit chance, and defense multipliers - showing you the Real Combat Performance of your forged items.

We don’t just look at base damage. For example, a Rivalite’s 20% Crit Chance is calculated as a probability to deal 50% bonus damage.

Effective DPS = Base Damage × (1 + Crit Chance × Crit Multiplier)

We mathematically convert this into a ~10% average damage boost to show you its true value over time.

Defensive ores like Darkryte, Mythril, and Obsidian boost your Defense stat.

Effective Health = Base Health ÷ (1 - Damage Reduction %)

Damage Reduction is treated as a massive boost to your total health pool, helping you compare "Health Ores" vs. "Defense Ores" fairly.

Our calculations are based on extensive community testing and in-game mechanics analysis.
