What is Lyonspyre?¶
Lyonspyre is a post-T2A spiritual continuation: vanilla Ultima Online Second Age combat math (pre-AOS damage, pre-AOS HP curves), a curated map of original Britannia rebuilt with custom tile art, and a layer of modern systems — talent trees, elemental resonance, leaderboards, multi-target boss aggro — bolted on top to give long-term progression and end-game depth that the original era never had.
Played with the Lyonspyre Client, a custom client that adds richer in-game panels (talents, leaderboard, profile, cooldowns) on top of the classic gameplay window.

Wiki conventions¶
- Formulas are shown verbatim — if a page shows
15000 / ((Stam+100) * Speed), that's the exact math the engine runs. - Versioned content is dated. When a system changed, the page says when and what the prior behaviour was.
- Cross-references use the
[[link]]style — every formula links to the page that documents it in depth. - Search is instant — hit / or click the search bar; results highlight as you type.
