Hit and Evade Rate

Basic Hit Rate

= (Hit stat / 2 + 140) * pilot's Terrain Rating + weapon's Hit + other modifiers

Basic Evade Rate

= (Evade stat / 2 + unit's Mobility) * pilot's Terrain Rating + other modifiers

Hit Rate

= (Basic Hit Rate - Basic Evade Rate) * defending unit's size + distance modifier + Command modifier - terrain bonus

Final Hit Rate

= Hit Rate + final modifiers

Notes

• "Other modifiers" includes Telekinesis, Genius, Potential, Friendship, and certain Ace Bonuses.
• "Final modifiers" includes Predict, Precognition, and certain Ace Bonuses.
• The distance modifier base range is 5 squares away from a unit. The distance modifier increases by 3% per square closer to the unit and decreases by 3% per square further away from the unit.
• For the purposes of the Basic Hit Rate formula, a weapon or attack that forces a unit to travel to the terrain of an enemy unit causes that weapon or attack to use the Terrain Rating of the terrain that the enemy unit is on.

Critical Hit Rate

Critical Hit Rate

= Attacking pilot's Skill stat - Defending pilot's Skill stat + weapon's Critical Rate + other modifiers

Notes

• "Other modifiers" includes Genius, TK, Rival, and Ace Bonuses.
• Critical hits deal 1.25x damage.
• Critical hits cannot occur if a pilot has Valor or Soul active.
