These are additional enchants, which come with the Sindusk server mod package. Some of these may not be enabled on Mythmoor.
Endurance (Jewelry): Reduces stamina loss. This has no conditionals and will work at all times, whether you're improving items, digging a road, or simply moving.

Prowess (Jewelry): Increases Combat Rating. This affects your ability to hit and evade in combat.
Acuity (Jewelry): Reduces favor cost. This effect only applies to spells with a favor cost over 10.
