Reagents
In the real world, a reagent is something added to a system to cause a chemical reaction, or added to test if a reaction occurs.[1] In Ultima Online, a reagent operates in a similar manner. They are used by spellcasters to cast spells, by scribes to create spell scrolls, and by alchemists to create potions.
Reagents can be looted from various mobiles, found on the ground, or purchased from NPCs. By default, NPCs sell up to 20 of the reagents they carry, but if they sell out of a given reagent, the next time they refresh their inventory, the amount they have for sale will double. This can be repeated until they reach a maximum of 999 for sale at a single time.
Reagents can also be deeded with Commodity Deeds by players in amounts up to 60,000 per deed, or bought and sold by players' Magincia Vendors.

Reagents of Old
These reagents come from old systems that never went live, though the reagents made their way into the game. These were originally introduced into the Ultima series with Ultima VIII: Pagan and Ultima VII: The Serpent's Isle, which has led to their commonly being referred to as Pagan reagents. Most are no longer spawning.
