Goblet of Saintly Surge

Once per room, the amount of healing is doubled when the wearer drinks a potion. If the potion has non-HP-restoring effects, the HP healed is still doubled, but the side-effects are not doubled.

Q1) What potions are healing potions?
A1) To be used in conjunction with Goblet of Saintly Surge, the healing token must restore HP expressed as an integer, not a variable such as “half” or “all.”

Q2) How does this interact with other items that modify healing potions (e.g. Greater Alchemist Pouch, Girdle of Wealful Health).
A2) Per the rules for Magical Damage Resolution, apply point-based modifiers before the doubling effect. Example: a 3 HP healing potion receives a +1 HP bonus from Girdle of Wealful Health, and the resulting 4 HP gets doubled to 8 HP from Goblet of Saintly Surge.

Q3) How does this interact with other items that share healing potions (e.g. Flask of Sharing, Lotus Blossom Bowls).
A3) Only the character drinking the potion benefits from the Goblet of Saintly Surge.
