Add nodes based on your map
Click the potion to attach a potion to the most recent node
Click nodes or potions to remove them.
The chance for a potion at the start of the act is 40%. After each combat, the chance increases by 10% if no potion was dropped or decreases by 10% if a potion was dropped. Elites get a flat 12.5% bonus chance to gain a potion, which doesnt carry over anywhere.
Question marks have a 10% base chance to be a combat. After a non-combat event, the chance increases by 10%. After a combat, it gets reset to 10%
This calculator ignores the chance for events to lead to a
combat such as "Punch Off", as it is relatively
insignificant.
However, if you are dropped a potion from
such an event, you may still append a potion to an event node
Slay the Spire 2 is still in early access and probabilities may
change over time. I will update this website to the best of my
ability.
This calculator is up to date as of update v0.107.1
Include past floors of only this act, and include when the
potions were dropped.
You can ignore shops, treasures, and
rest sites.
Include events and whether or not they are
enemy events. Shop and treasure events should be treated as
normal events
Include all floors up until the encounter you are interested in
