Enhance Potions and drinking rules

From UO:PvE Wiki

Enhance Potions scales supported potion amounts, with an additional bonus from Alchemy.

Development source reviewed on 29 October 2026. In-game availability is unverified.

Effective enhancement#

For an ordinary player in the current expansion, effective enhancement E = min(gear Enhance Potions, 50) + floor(Alchemy × 10 / 33). The gear cap applies before the Alchemy addition. Effective Alchemy is used.

Supported integer amounts are scaled as floor(amount × (100 + E) / 100). Supported chance values use the same multiplier without integer rounding. Not every potion scales every property: Strength and Agility potions scale their stat bonus while retaining their fixed duration.

Drinking#

A potion must be movable and within 1 tile. Normal drinking reveals the character, consumes the potion and returns an empty bottle, subject to duel consumption exceptions. Most ordinary potions require a free hand. A balanced ranged weapon is explicitly allowed by the hand check; a two-handed weapon otherwise occupies the needed hand space.

Explosion potions waive the free-hand requirement but have their own casting, paralysis and throw restrictions. See Stat and explosion potions.

Buff stacking#

Strength and Agility potions use the same positive magic stat-buff channel as corresponding spells. An existing bonus that is equal or larger prevents a weaker new bonus; a stronger bonus replaces it. The bonuses are not added together. Effective stat limits still apply.
