Dragon's Blood

So powerful is this creature that the blood burns as if aflame. Precise measurements of this are wise, for too much and the magic will go dangerously awry.

Originally appeared in Ultima VIII as a Thaumaturgy reagent, it was to have been used in Ultima Online as a reagent for the (originally canceled) Necromancy system.

On most shards it is now a rare item, part of a set commonly called Pagan Reagents.
