Part descriptions
Ancient Acidic Gland
A throat gland that reeks of acid fumes; it brews the fluid behind a dragon’s breath.
Use: swallow it (action) and make a DC 15 Constitution save. Failure – you take 3d8 acid damage. Success – you breathe acid in a 45-foot line, 5 feet wide; each creature there makes a DC 15 Dexterity save, taking 7d8 acid damage on a failure or half on a success.
Good for: breath and acid items.
Ancient Black Draconic Blood
Midnight-black dragon blood with a faint arcane spark in it.
Use: can replace the magic ink for copying spells into a spellbook – it covers up to 100 gp of ink.
Good for: scrolls (excellent fit).
Ancient Black Draconic Heart
A black, leathery dragon heart with a dim glow – said to hold the dragon’s pride and might.
Use: eat it (action) and make a DC 15 Wisdom save. Success – you can’t be frightened for 24 hours.
Good for: items that cause or resist fear, and dragon-themed items (excellent fit).
Dense Gills
Gills with a tightly packed mass of feathery membranes – a creature with them breathes underwater with ease.
Good for: water-breathing items (excellent fit).
