Is Toolbox good in Slay the Spire 2?

Its standout card pairing is Abrasive, which lifts the relic’s win rate by +48.8% when both are in play. It also works nicely with Expose, good for a +43.7% win-rate change. It typically enters the deck near floor 25. As a shop relic, how often it’s offered depends on its rarity tier.

Pick or Skip: Toolbox

Players take Toolbox in 15.3% of the 1337 offers it appears in; those runs win 44.6% against 28.1% for runs that passed, a pick lift of +15.7% over 204 decided runs.

Taken 205 times out of 1337 offers.

Pick rate when offered counts offers, not runs: out of every time the game put this in front of a player, how often it was taken. It is not the same number as the share of runs that end up containing it.

Pick lift is the sample-adjusted gap between runs that took the option and runs that passed on it. It is the fair way to rank choices, because raw win rates put the smallest samples on top.
