Secret Craft References

  • Activation Costs: 1 SB point per circle for Manifestation, Enhancement, Power and Downtime Activity unless otherwise specified.
  • Secret Craft Attempt = d20 + Prof + Abi mod + circle achieved.
  • Craft Check: The craft check is a d20 plus your proficiency and the associated attribute modifier. This craft check must use the language associated with the craft as part of the check. You add your circle level to the roll with Initiates being +0. For every 5 points you exceed the target number you reduce the Soul Burn cost by 1. For every point you fail the roll by, you can choose to succeed by adding those point to the soul burn cost as long as it was not a critical failure.
    • Base Critical Failure: A roll of a 1 on the craft check is a curse from your patron, and you suffer a mishap. The standard thing that happens is that you increase your soul burn by the Crit Effect Modifier, then it reduces your hit point maximum by the Crit Effect Modifier, and lastly it causes hit point damage equal to the Crit Effect Modifier. Check each of the crafts for what additional effect happen during a mishap.
    • Base Critical Success: A roll of a 20 on this check is a blessing from your patron, and you are granted a boon. The standard thing is that you reduce your Soul Burn by the Crit Effect Modifier, then it can restore damage to your maximum hit points by the Crit Effect Modifier, and lastly it refreshes you repairing hit points equal to the Crit Effect Modifier . Check each of the crafts for what happens during a boon.
    • Crit Effect Modifier: This is 1 + circle ability level + character level.
      • So a 8th level character using a 2nd circle ability would have a crit effect modifier of 11.
      • A 4th level character with a 1st circle ability would have a modifier of 6.
      • A 12th level character with s 3rd circle ability would have a modifier of 16.
      • A 16th level character with a 4th circle ability would have a modifier of 21.
      • A 20th level character with a 5th circle ability would have a modifier of 25.
  • Craft DC: The Base DC of a secret craft abilities is: Base Craft DC = 8 + Prof + Ability mod + circle achieved.
  • Manifestation – Lasts until the end of a long rest, you expend it, or you dismiss it as a free action. You can extend a craft manifestation for 1 soul burn after a long rest to last until your next long rest without the need for a craft check. Manifestations gives you access to Manifestation Aspects, Enhancements and Powers.
  • Manifestation Aspect – Selected as the version of the manifestation used when you activate the Manifestation.
  • Enhancement – Lasts as long as the manifestation is active.
  • Power – Has a limited duration, but needs the manifestation active to use.
  • SB – Soul Burn. Each point of Soul Burn is a reduction to your maximum hit points. If your Soul Burn ever reduces your hit point total to zero your character is destroyed based in the craft and sponsor. Soul Burn can be recovered via downtime or other methods all with GM approval.
