Character
Select or add a character above to assign traits.
Weapons carried
Select a character on the Characters tab, then tick what they carry and what they know. A character can only strike with weapons equipped here and only cast spells learned here. Unarmed melee is always available and needs no weapon. New weapons are defined in GM tools.

Armour

Shield

Weapon editor
Add or remove weapons available to the whole cast. HP damage is applied on a strike. Damage type: slashing can open a bleed, blunt can daze, piercing is clean and ignores armour. Elements are negated by matching immunity. A weapon that requires reload holds one shot and must be reloaded as a full action before it can fire again.
Melee
Ranged
Spells learned
Select a character first.
Battle tracker
Create a battle, add fighters to each side, then start it. Mark each side as attacking, defending, or surprised to reflect how the fight began; this shifts to-hit chances both ways. Initiative is rolled fresh at the top of every round: a d10 plus Dexterity. The fighter whose turn it is shows their own choices on the card. Multiple battles can run at once.
Battle log
Concluded battles are recorded here.
