Mana regeneration and Meditation
From UO:PvE Wiki
Meditation, Intelligence, armor and Mana Regeneration combine into a timed one-mana recovery rate.
Development source reviewed on 29 October 2026. In-game availability is unverified.
Current-era formula#
Let M be effective Meditation and I effective Intelligence. Meditation points = (I+3M)×0.025 below 100 Meditation, or (I+3M)×0.0275 at 100 or more. Any meditation-blocking armor sets these points to 0.
While actively meditating, add another min(meditation points,13). Separately combine effective equipment Mana Regeneration with the form bonus: Vampiric Embrace adds trunc(3×Necromancy strength), or Lich Form adds trunc(13×Necromancy strength). Cap this equipment-plus-form subtotal at 18.
Add the Meditation and equipment / form subtotals, clamp to at least −1, then floor to a whole number P. Mana interval =10÷(2+P) seconds per mana. Equipment MR itself is capped at 2 / 4 / 6 / 10 by progression.
Examples without blocking armor or a form#
| Int / Meditation / equipment MR | Passive interval | Active Meditation interval |
|---|---|---|
| 100 / 100 / 0 | 0.769 s | 0.417 s |
| 100 / 100 / 6 | 0.526 s | 0.333 s |
| 150 / 120 / 10 | 0.385 s | 0.256 s |
Armor and entering Meditation#
Neck, gloves, head, arms, legs and chest armor are checked. Armor with Mage Armor or Spell Channeling contributes no blocking penalty. Otherwise any positive meditation penalty removes the Meditation contribution entirely under the current rules. Shields are not part of this current-era armor-penalty sum.
The active Meditation success chance is (50+2×(Meditation−missing mana))÷100, compared with a random 0–1 roll. A successful attempt enters meditation; the skill’s reuse delay is 10 seconds. A pending target or blocking armor prevents the attempt. Incompatible held equipment is moved to the backpack when a player meditates.
