Spell schools and mana
From UO:PvE Wiki
Magery, Necromancy and Chivalry are enabled, with different casting, damage and resource rules.
Development source reviewed on 29 October 2026. In-game availability is unverified.
Skills behind each school#
| School | Casting skill | Damage or power skill | Other resources |
|---|---|---|---|
| Magery | Magery | Evaluating Intelligence for standard damage | Spell-specific reagents or scrolls |
| Necromancy | Necromancy | Spirit Speak | Spell-specific necromantic reagents or scrolls |
| Chivalry | Chivalry | Chivalry; some power calculations also use karma | Tithing points |
Magery base mana costs#
Mana reduction and other modifiers can change the final cost. These are the base costs before those adjustments.
| Circle | Base mana |
|---|---|
| 1 | 4 |
| 2 | 6 |
| 3 | 9 |
| 4 | 11 |
| 5 | 14 |
| 6 | 20 |
| 7 | 40 |
| 8 | 50 |
Casting difficulty#
Under the current rules, a Magery scroll uses a casting-difficulty entry two circles below the equivalent spellbook cast. Its normal circle-based mana cost remains. Necromancy checks from a spell’s required skill to 40 points above it; Chivalry checks from its required skill to 50 points above it. A listed minimum therefore does not promise a successful cast.
Resource limits#
The general spell mana calculation caps effective Lower Mana Cost at 40%, with progression equipment limits able to restrict the effective attribute further. Chivalry checks tithing and mana separately; its zero value in the shared spell-mana method does not mean Chivalry is free.
