Stable Serum FAQ
- Is Stable Serum good in Slay the Spire 2?
- Stable Serum is a Uncommon potion: Retain your Hand for 2 turns. It is a Colorless potion, so any character can roll or buy it. Rarer potions tend to swing harder, so weigh the immediate payoff against holding a slot open for an emergency.
- When should I use Stable Serum?
- Drink Stable Serum when its effect — Retain your Hand for 2 turns. — directly answers the floor in front of you, such as an elite, boss, or a turn you would otherwise lose tempo. Holding potions for the right moment usually beats spending them on trash fights.
