Draconis Fundamentum
Monstrous graft
- Properties: Internal Slot
Donor: Any Dragon with a Breath Weapon, Such as Fire Breath
This graft installs the source of breath weapons into your body. When you take the Attack action on your turn, you can replace one of your attacks with an exhalation of magical energy in a Cone. Each creature in that Cone must make a Dexterity saving throw, taking damage as shown on the Draconis Fundamentum table of the same type as the donor’s breath weapon, or half as much damage on a successful save. The breath weapon’s damage, save DC, and area of effect vary with the donor’s Challenge Rating, as shown on the Draconis Fundamentum table.
Once you activate this graft, you can’t do so again until you finish a Long Rest. You can also restore your use of it by expending a number of Hit Point Dice as shown on the Draconis Fundamentum table (no action required).
