Frequently Asked Questions
What is Effective Health Pool (EHP)?
Effective Health Pool (EHP) measures the total raw damage an enemy must deal to eliminate you before damage reduction. It is calculated as EHP = HP x (1 + Armor / K).
Should I prioritize Critical Rate or Critical Damage in RPGs?
As a general rule of thumb, maintaining a 1:2 ratio between Critical Rate and Critical Damage (for example, 60% Crit Rate to 120% Crit Damage above base) maximizes mathematical expected damage.
