The System
Roll d6s, Every 5 or 6 is a HitPlayers resolve actions by rolling pools of six-sided dice (d6s). Each 5 or 6 rolled is a Hit
. The number of hits determines the final outcome (e.g., Standard Checks: 2+ Hits = full success – 1 Hit = narrow success – 0 Hits = failure
).Most of the game's mechanics rely on this basic format, so once you understand this, you understand 90% of the game.Balancing your StaminaAs in most Soulslike games, characters can push themselves by spending Stamina
, in this case gaining extra dice for their rolls. But a character's remaining Stamina is also the basis for making Saves
to avoid dangers and incoming attacks.When you fail a Save
, you take Damage
but your Stamina
is fully restored so that you get back up and finish the fight.It's a constant balancing act to decide when to risk the most to hit the hardest.Items in the forefront
All Items
in your inventory have usage dots
. When all dots are marked, they are depleted or worn out.- For Weapons
, you mark usage to gain extra Damage
.
- For Armor
, you mark usage to absorb Damage
equal to its rating.
- For Spells
, you mark usage when you use them.You may spend time while resting to repair worn items or recharge your spells.Escalating CombatBosses and dangerous enemies are designed with Phases
, with each Phase
providing them Abilities
and powers until they reach a pinnacle of danger. More than whittling down hit points, combat is about being clever and working with your environment.
