Dragon Blood, Chromatic - Black
The blood of a Black Dragon courses through your veins. In addition to standard Dragon Disciple progression, you receive certain specific benefits befitting your Black Dragon ancestry.
At level 10 in the Dragon Disciple class, you receive total immunity to acid damage.
At level 3, you gain the ability to breath a 60 foot line of acid once per day. This line will cause 2d10 damage, increasing to 4d10 at level 7, 6d10 at level 10, with further improvements in epic levels.
