Reagent

A reagent is a consumable item required to cast certain spells. Reagents are the chemical matter of the realm's magic — pinches of herbs, fragments of bone, drops of essence — drawn from a pouch as a Magery, Necromancy, Alchemy, Inscription, or Mysticism caster shapes a spell. The Chivalry school is the sole exception, replacing reagents with tithe points; everything else, in some measure, runs on this slow-burning supply chain. Reagents can be purchased from NPC vendors, looted from monsters, harvested from the ground, or — in modern play — entirely sidestepped by stacking the Lower Reagent Cost item property to 100%.

How Reagents Work

Each reagent-using spell consumes a small fixed quantity of one or more reagents on cast. If a reagent is missing from the pouch the cast fails before mana is spent. A handful of mechanics modify the basic pull-from-bag behaviour:

• Lower Reagent Cost (LRC). An item property that, summed across worn equipment, gives a percentage chance to cast without consuming reagents. Equip enough LRC to total 100% and reagents are never consumed. Below 100% the chance applies independently per reagent: a 95% LRC suit casting a one-reagent spell consumes a reagent about 1 in 20 casts; for a two-reagent spell the probability of no consumption is 95% × 95% ≈ 90.25%, and so on.
• Chivalry. The Chivalry spell school does not use reagents at all. Instead its spells consume tithe points earned by donating gold at a shrine or chapel.
• Spellweaving and Bushido likewise do not use reagents.
• Necromancy and Mysticism do use reagents, drawn from their own dedicated pools.

Where to Find Reagents

• NPC vendors. Mage, Healer, Alchemist, Necromancer, Mystic, and Gargoyle Mage vendors carry reagents according to their type. Each vendor stocks up to twenty reagents of the kind they sell by default. The vendor stock-up trick: when a vendor sells out of a reagent, the next inventory refresh doubles the amount they offer for sale. Repeating the buy-out cycle scales the available stock up to a single-vendor maximum of 999, after which it caps. This makes any frequented vendor a reliable bulk source for stockpiling guildmates.
• Loot. Many monsters drop reagents in their corpse loot, including some that drop reagents found nowhere on a vendor (notably Daemon Bone and Dragon's Blood).
• Spawning on the ground. Certain regions of Sosaria and Ilshenar host fixed reagent spawns that can be picked up by hand.
• Player-to-player trading. Magincia Vendors and Commodity Deeds let players move reagents in bulk: a single Commodity Deed holds up to 60,000 of a single reagent.

Magic Reagents

Used for Magery, Inscription, and Alchemy spells, and for the bulk of Mysticism casting. These eight are the foundation set every mage carries:

1. Black Pearl
2. Blood Moss
3. Garlic
4. Ginseng
5. Mandrake Root
6. Nightshade
7. Spiders' Silk
8. Sulfurous Ash

Inscription scrolls and Alchemy potions both draw from this same pool, sometimes with a small quantity adjustment.

Necromantic Reagents

Used for Necromancy spells and a small number of Alchemy recipes. Necromancy draws on its own set of five:

1. Batwing
2. Daemon Blood
3. Grave Dust
4. Nox Crystal
5. Pig Iron

Mysticism Reagents — the Pagan Set

Mysticism spells use the eight Magic Reagents above and additionally call for four special Pagan Reagents of their own:

1. Bone
2. Daemon Bone
3. Dragon's Blood
4. Fertile Dirt

The Pagan label reflects their origin in earlier Ultima titles — see Reagents of Old, below.

Peerless Reagents

A separate class of reagents drawn from defeating the realm's Peerless boss creatures. These are crafting-only ingredients, not spell components, and feed Imbuing and Peerless-tier item recipes:

Reagents of Old

A wider set of reagents survives in the realm from Ultima titles whose magical systems were never fully implemented in UO. Most of these are no longer spawning; a handful (notably Bone, Daemon Bone, Fertile Dirt) found new homes in modern systems. Together they are commonly called Pagan Reagents, after the Ultima VIII title where many were first introduced.

Original Necromancy Reagents (Ultima VIII: Pagan)

These were originally intended for an early UO Necromancy implementation that did not ship in its planned form. The Necromancy that was eventually delivered uses a different reagent pool entirely.

• Blackmoor
• Bone — now used for Mysticism spells.
• Dead Wood — called simply "Wood" in Pagan.
• Executioner's Cap — "Executioner's Hood" in Pagan.
• Fertile Dirt — "Dirt" in Pagan; now used in Gardening and for Mysticism spells.
• Vial of Blood — "Blood" in Pagan. Note that all Vials of Blood were renamed to Daemon Blood when Age of Shadows shipped.

Serpent Isle Magic (Ultima VII Part 2)

• Blood Spawn — "Bloodspawn" in Serpent Isle. (Hue 0 graphic 3964.)
• Serpent's Scale — "Serpent Scales" in Serpent Isle, originally a Thaumaturgy reagent in Pagan.
• Wyrm's Heart — "Worm Heart" in Serpent Isle.

Sorcery Reagents (Ultima VIII: Pagan)

• Brimstone
• Daemon Bone — "Daemon Bones" in Pagan, now used for Mysticism spells.
• Obsidian — note that the 20th Anniversary Event Obsidian uses a different graphic.
• Pig Iron — now used for Necromancy spells.
• Pumice (graphic 3979).
• Volcanic Ash — note that all Volcanic Ash was renamed to Grave Dust when Age of Shadows shipped.

Thaumaturgy Reagents (Ultima VIII: Pagan)

• Batwing — "Bat Wing" in Pagan, now used for Necromancy spells.
• Dragon's Blood — Mysticism uses a distinct version of the graphic to keep the modern reagent separate from the original.
• Eye of Newt (graphic 3975).
• Serpent's Scale.

Other Rare Reagents

Beyond the working sets and the Pagan lineage, a long tail of variant reagents exists as collectibles or curiosities — created by old quests, bugs, or seer-driven events.

Newbiefied Reagents

In the early game, new-player starting inventory was "newbiefied" — blessed without showing the blessed tag. Each of the eight Magic Reagents existed in a newbiefied form. Stacking newbiefied reagents with unblessed ones loses the blessing on the entire stack:

• Newbiefied Black Pearl, Bloodmoss, Garlic, Ginseng, Mandrake Root, Nightshade, Spiders' Silk, Sulfurous Ash.

Blessed Pagan Reagents

Generated by the original Paladin quest Uzeraan's Turmoil, which has been disabled since the release of Age of Shadows:

• Blessed Daemon Bone, Blessed Fertile Dirt, Blessed Vial of Blood.

Glacial Reagents

A small set of hue-shifted reagents handed out at an EM event on Chesapeake in 2013:

• Black Pearl (hue 1152), Bloodmoss (hue 1151), Mandrake Root (hue 1150), Sulfurous Ash (hue 1153).

Rubble Reagents

Created during the destruction of Magincia event arc. Each shows the name "Rubble" instead of the reagent name:

• Magery rubble: Bloodmoss, Garlic, Ginseng, Mandrake Root, Nightshade, Spiders' Silk.
• Necromancy rubble: Blackmoor, Bone, Daemon Bone, Grave Dust, Nox Crystal, Wyrm's Heart.
• Sorcery rubble: Obsidian, Daemon Blood.
• Thaumaturgy rubble: Bat Wing, Dragon's Blood.

Golden Bloodmoss

A bug from the addition of Trammel produced a single hue-149 Bloodmoss variant, which has since become a server-tier rare.

Blackrock Reagents

Hue-shifted Blackrock reagents from various seer-run events. Not to be confused with the unprocessed forms (small pieces and ordinary pieces of Blackrock).

• Blackrock (hue 1107)
• Blackrock (hue 1109)
• Crystalline Blackrock

Server Birth Reagents

When the shards first went live, a number of server birth reagents existed in the world. They can still be visited in their original positions but cannot be picked up. Server birth reagent variants exist for Garlic (graphics 6369–6372), Ginseng (6377–6378), Mandrake Root (6365–6366), and Nightshade (6373–6376) — Nightshade graphic 6375 in particular is visually identical to ordinary spawning Nightshade despite being a different item internally.

Stacking Bug Reagents

A long-since-fixed stacking bug reset the name of stacked items to the default name for the underlying graphic, producing legitimate but anomalous reagent variants:

• Bloodspawn hue 537 — created from Cocoa Pulp.
• Eye of Newt hue 1174 — created from a Lucky Coin.
• Pumice in hues 121, 149, 183, 211, 239, 491, 551, 634 — each created from the matching Trammel Moonstone.
• Pumice hue 2499 — created from an Ancient Moonstone.

20th Anniversary Event Reagents

A bespoke set of reagents found in treasure chests during the 20th Anniversary event, used for the Thaumaturgy, Pagan Necromancy, Sorcery, and Theurgy spell schools available during that event:

• Black Candle, Red Candle, Blackmoor, Executioner's Cap, Pagan Obsidian (different graphic from the original Pagan reagent), Pumice.

Blackrock

A long-standing oddity of the realm: samples of Blackrock can be found in display cases throughout Sosaria, and various forms have appeared in seer events, but the substance has never been given a confirmed in-game use as a reagent. It remains one of the unresolved mysteries of the Origin / EA Games transition.

NPC Vendor Matrix

NPCs of different classes carry different reagent subsets. The matrix below summarises what each vendor type sells:

Daemon Bone and Dragon's Blood do not appear on any standard NPC vendor — they must be looted, harvested, or traded between players.

Practical Notes

• The all-LRC mage suit. Most modern Magery characters wear an LRC-100% suit, which trivialises bag management for everyday casting. Reagents are still consumed by Inscription crafting and by Alchemy recipes regardless of LRC.
• Chivalry's economy. With Chivalry tithed at gold-for-tithe-points instead of consumed reagents, paladin builds bypass the reagent supply chain entirely — a substantial early-game advantage.
• Bulk supply. A guild that runs reagent buy-outs on the same NPC across all eight Magic Reagents can fill a single Commodity Deed (60,000 reagents) within a few cycles.
• Hue-shift collectibles. The variant sets above (Glacial, Rubble, Newbiefied, Server Birth) are collectible, not strictly mechanically distinct from their ordinary counterparts. Many of them will function as ordinary reagents if used in casting; collectors generally do not.
