Ultima Online Spellweaving spell list
For official shards · 16 entries · every figure sourced
Every Spellweaving spell, what it does, the skill it needs and what it costs. The descriptions are uo.com’s own words and the minimum skills come from the school’s published table.
Open this book in the toolkit → — it works out your real chance to cast each one at your own skill, and shows the icons from the game.

What the minimum skill actually buys you
The minimum is where a spell becomes castable, not where it becomes reliable. The chance to cast comes down to one line, and it is the same line for every book [!]:
Chance to cast = ( ( Skill − ( Difficulty − ( Casting Focus ÷ 2
) ) ) ÷ Casting Focus )
Casting Focus is 40 for Magery and Necromancy and 50 for the rest [!]. What the two groups do not share is where the minimum sits inside that line: Chivalry, Magery and Necromancy start at 0% and reach 100% one whole Focus above it, while Bushido, Ninjitsu, Mysticism and Spellweaving start at 25% the moment they can cast at all. That is why a Bushido ability feels dependable so much sooner than a spell of the same nominal level — it is not a feeling, it is two different lines. The toolkit works that out for your skill →
Where these come from
uo.com’s Spellweaving page for the descriptions and the published minimums. uo.com does not publish the chance-to-cast line or the Casting Focus values, so they are unpublished and carry a [!]. Everything here is from uo.com or the game itself; anything uo.com does not publish is marked [!] as unpublished.
