A dragonpact is a spellpact forged between a spellcaster and a powerful dragon, made possible due to the draconic blood they share. Typically, only spontaneous arcane spellcasters may attempt to form a dragonpact. A dragon speaker may also form dragonpacts, but their pacts are formed differently than what is described herein.
Only a true dragon can grant the benefits of a dragonpact, and no true dragon can ever be the recipient of a dragonpact.
Costs of a Dragonpact
| Spell Slot | Spellcaster Gold Cost | Dragon Hit Point Cost |
|---|---|---|
| 2nd | 400 | 10 |
| 3rd | 900 | 15 |
| 4th | 1,600 | 20 |
| 5th | 2,500 | 25 |
| 6th | 3,600 | 30 |
| 7th | 4,900 | 35 |
| 8th | 6,400 | 40 |
| 9th | 8,100 | 45 |
| 10th | 10,000 | 50 |
To form a dragonpact, the spellcaster must offer the patron dragon treasure equal to the level of the sacrificed spell slot squared × 100 gp. So, for a 3rd-level dragonpact, the sorcerer must typically offer 900 gp (32 × 100). A dragon may accept gold, gems, art objects, or magical items, though most dragons have a strong preference for the items they desire.
The result of the spellcaster’s negotiation check affects the final cost of the dragonpact.
A failed negotiation check does not prevent the dragonpact from being formed. However, it increases the cost of the pact by one spell level. So, a 3rd-level dragonpact would cost 1,600 gp (42 × 100) after a failed check. Similarly, if the spellcaster succeeds on his negotiation roll by 10 or more, the cost of the pact is reduced by one spell level. So, a 3rd-level dragonpact would cost him a mere 400 gp (22 × 100).
Regardless of the negotiation roll, the patron dragon’s maximum hit points is reduced by 5 per spell level as long as the pact remains active.
