Health and stamina regeneration
From UO:PvE Wiki
Regeneration attributes change the interval between one-point recovery ticks.
Development source reviewed on 29 October 2026. In-game availability is unverified.
Health regeneration#
For an ordinary player, begin with effective equipment Hit Point Regeneration. Humans add 2. Clamp this subtotal between 0 and 18. Horrific Beast then adds trunc(20×Necromancy school strength) after that clamp. Health tick interval =10÷(1+points) seconds. Each eligible tick restores 1 health.
Equipment HPR is separately capped at 2 / 4 / 8 / 12 by progression band. The 18-point calculation cap is therefore not an extra 18 points you can add to equipment. Human racial regeneration is included before that cap.
Health examples without a form#
| Equipment HPR | Human interval | Elf interval |
|---|---|---|
| 0 | 3.333 s | 10 s |
| 2 | 2 s | 3.333 s |
| 4 | 1.429 s | 2 s |
| 8 | 0.909 s | 1.111 s |
| 12 | 0.667 s | 0.769 s |
Stamina regeneration#
For an ordinary player, stamina points = min(24, effective equipment Stamina Regeneration + Vampiric Embrace bonus). The form bonus is trunc(15×Necromancy school strength). Clamp the final points to at least −1. Stamina tick interval =10÷(2+points) seconds, restoring 1 stamina each eligible tick.
With no equipment or form, the interval is 5 seconds. At 12 equipment points it is about 0.714 seconds. At the 24-point combined ceiling it is about 0.385 seconds. Focus is retired and does not add regeneration here.
Eligibility#
These ordinary player regeneration timers require being alive. The engine’s current default permits natural health regeneration while poisoned. This does not make a poisoned player eligible to drink a healing potion, and damage still interrupts bandaging.
