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.
