3 cores, 1 body. Due to this strange biology, you have three different forms with separate powers.
Cursed Energy
Beginning at 1st level, you can harness your negative feelings into a usable source of energy called cursed energy. These feelings can be harnessed into attacks or abilities. The amount of cursed energy you possess is based on your class. Some classes use a modifier, either Charisma or Wisdom (player’s choice).
Your Cursed Energy DC is 8 + your Cursed Energy ability modifier + your proficiency bonus.
First Core
Starting at 1st level, your cursed energy is gathered into a single core. You gain 1 extra hit point per level.
Second Core
At 3rd level, you manifest your cursed energy into a second core. As a bonus action, you can choose to activate a secondary form, giving you access to a specific technique. This technique is one of the following:
- Unblockable Blows. At the cost of 1 Cursed Energy per attack, you can bypass resistances. If the creature doesn’t have resistances, it counts as vulnerable.
- Energy Blast. As an action, you can spend as much Cursed Energy as you wish and make a ranged Cursed Energy attack. On a hit, the target takes Xd6 force damage, where X equals the Cursed Energy spent.
- Defensive Form. After activating this form, you are better defensively. You gain temporary hit points equal to 5 × your Cursed Energy modifier.
Third Core
Beginning at 6th level, you gain another core option.
Insurance
Starting at 11th level, as a reaction after falling to 0 hit points, you can lose access to this form for 1 week and return with hit points equal to half your hit point maximum.
Domain Expansion: Rule of Threes
At 18th level, you gain true understanding of your cores. When inside your domain, you count as under the effect of all your cores.
