Moving casts and Hamstring
From UO:PvE Wiki
Players can move while casting the three supported schools. Hamstring is a separate player-versus-player movement ability.
Development source reviewed on 29 October 2026. In-game availability is unverified.
Moving while casting#
Moving casts are enabled for Magery, Necromancy and Chivalry. This removes the normal casting movement block; it does not remove other restrictions such as paralysis or ordinary spell interruption.
Using Hamstring#
Use [Hamstring and choose another living player whom you are allowed to harm. This ability does not target monsters.
| Requirement or effect | Value |
|---|---|
| Weapon | A melee weapon equipped |
| Tactics | 70.0 or higher |
| Cost | 15 mana and 10 stamina |
| Range | Within 4 tiles, same map, visible and in line of sight |
| Restrictions | Cannot use while frozen, paralyzed or holding an active spell |
| Slow duration | 2 seconds |
| Your cooldown | 15 seconds |
| Target immunity | 10 seconds from the successful application |
What the slow does#
The target can still cast and fight. The effect limits forward movement steps to one every 600 milliseconds while it lasts; turning is permitted.
