• Attack chance: (unit agility - unit stress) - (target agility - target stress) + base chance | minimum 1
• Attack chance when Stunned: (unit agility - unit stress) + target stress + base chance | minimum 1
• Critical attack chance: (unit luck - unit stress) - (target luck - target stress) | minimum 1
• Modification chance: (unit intelligence - unit stress) + base chance | minimum 1
• Stun Chance: (physical damage - unit stress) - (target physique - target stress) | minimum 1
• Retreat Chance: unit stress | minimum 0
• Critical Miss Chance: unit stress | minimum 0

Game Phases

• Prepare Unit Phase - Unit can be placed on any available position before battle starts. Only Equip or Unequip actions can be performed during this phase.
• Move or Action Phase - During this phase Move, Use, Equip, Unequip, Wait or Skip actions can be performed while actions points remains more than 4
  • Use action - Can be performed with weapon, magic and disposable items. Reduces required actions points.
  • Move action - Requires 4 action points
  • Equip or Unequip action - Can be performed with equipment any time and requires no ation points.
  • Wait action - moves unit to the back of the queue and keeps all unused action points.

Mechanics:

• Critical Damage - Doubles the damage.
• Critical Miss - If a unit's attack misses and the unit's Stress attribute is more than zero then Critical Miss check is performed. A unit can damage itself with double damage.
• Exhaustion - Any Instant Physical Damage absorbed by unit's equipment accumulates to the exhaustion damage. But cannot be enhanced with opponent's intelligence attribute. If a unit is hit while totally exhausted (stamina is zero), critical damage is dealt.
• Stun - Any Instant Physical Damage can cause stun. When stunned, a unit loses its turn in the current round and appears at the end of turn queue in the next round. If a unit is hit while stunned, critical damage is dealt and the stun is reset.
• Retreat - If Stress attribute is more than zero, before each unit turn the Retreat check is performed. A unit can miss its turn by moving to a corner of the battlefield.
• Equipment Wearout - Each success action followed by damage, or each action that requires ammunition, increases the Wearout of unit weapon, as well as Wearout of target equipment. If Wearout of an item reaches its Durability, the item can no longer be used and becomes unequipped.
