Combat

The blow, in order

1. The hit. An attack meets accuracy against evasion: 75% + (accuracy − evasion) ÷ 10, never under 1% or over 99%. An ability that asks a save rolls the save instead; one that is sure never misses.

2. Block, then parry. A landed blow may be stopped by the target's shield (block) or turned by its weapon (parry), each 10 points 1%. No creature blocks or parries.

3. The roll. The weapon's own range, or a creature's, or the ability's damage.

4. Power. × power ÷ 100; a staff's or a sceptre's bolt × spellcraft ÷ 100; an ability × its potency ÷ 100.

5. The crit. At crit chance less the target's crit resistance over 100, the blow deals × (1 + crit damage ÷ 200).

6. Armour or resistance. A blunt, piercing or slashing blow meets the target's armour of that type: each 10 points over 100 take 1 off, less 1 for each 10 points of the attacker's penetration over 100; under 100, armour adds. A magic blow meets its resistance instead, in full.

7. Rounded. Half up, and never under 1.

8. Life steal. Each 10 points over 100 heal the striker 1% of the health the blow took.

The hit

75% when accuracy and evasion are even; every 10 points between them move it 1%, from 1% to 99%: nothing is ever certain.

The save

An ability that names a save is shrugged off at 50% + (save − potency), each point 1%, from 1% to 99%. A save halves the blow or stops it whole, as the ability says; what it carries (a stun, a slow) saves on its own once the blow lands. Each attribute has its save and its potency: Strength the Stance save and Might potency; Dexterity the Reflexes save and Finesse potency; Constitution the Endurance save and Fortitude potency; Intelligence the Wits save and Cunning potency; Wisdom the Will save and Insight potency; Charisma the Courage save and Presence potency.

Armour and resistances

Armour is three stats, one for each kind of weapon blow: Blunt armour, Piercing armour, Slashing armour. Resistances are ten, one for each kind of magic: fire, frost, lightning, thunder, acid, poison, arcane, holy, shadow and mind. Armour stops weapons and resistances stop magic; neither touches the other, and no attribute raises them: only gear and abilities do. Each 10 points over 100 take 1 off a blow; under 100 is a weakness that adds.

Creatures by tier and rank

A creature is made by the same rule as a hero: its attributes multiply 100 plus its own points. Each tier of its land above the first adds 30 Health, 30 Power, 10 Accuracy, 10 Evasion, 10 Penetration, 5 to each save and potency, 10 Perception, and its armour and any resistance over 100 grow by 70% of what they have over it (a weakness stays as it is). Experience grows 100% a tier.

The Orc, tier by tier:

A rank makes a creature's final health and power a share of a common one's, and rolls its loot more times:

Mana and breath

Every ability spends breath, × 100 ÷ breath efficiency. Spells and bolts spend mana as well, × 100 ÷ spell efficiency, rounded up and never nothing; a staff's or a sceptre's bolt costs 1. Mana is a burst, not a stream: at wellspring 100, 1% of the pool comes back every 10 min. Out of mana, a staff swings blunt, with power.
