Bone Brew FAQ
- Is Bone Brew good in Slay the Spire 2?
- Bone Brew is a Uncommon potion: Summon 15. It is most associated with the Necrobinder, but potions drop for any run. Rarer potions tend to swing harder, so weigh the immediate payoff against holding a slot open for an emergency.
- When should I use Bone Brew?
- Drink Bone Brew when its effect — Summon 15. — 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.
