Salvo Attack

Is Salvo good in Slay the Spire 2?

In Slay the Spire 2, Salvo is a rare attack from the Colorless card pool. Its effect: Deal 12 damage. Retain your Hand this turn. Right now it’s a premium pick that sits at B tier — one of the better cards you can add to a deck this run.

Over 36 tracked runs its win rate sits at 48.6%, 35.1% ahead of the 13.5% all-deck baseline. It sees niche play, included in only 0.2% of eligible runs. It is taken in 0.5% of the 1276 offers recorded so far, split 6 runs that took it against 1202 that passed — not yet enough decided runs on either side for a pick-versus-skip win rate. Within Ironclad runs it’s drafted 0.4% of the time, making it a regular part of that class’s decks. Decks that include it run about 1.2 copies on average.

On the relic side, Bag of Marbles is its standout companion, worth a +20.1% win-rate swing alongside it. It costs 1 energy, gets upgraded 34.9% of the time, and tends to be picked up near floor 19.

Upgrading the card adds +4 Damage to its stat line. Of the runs that drafted it, 17 ended in victory against 18 deaths and 1 abandons. Its most common run-ender is The Insatiable Boss, finishing 8.3% of the runs it shows up in. See the synergies, class split, and threats below for the full picture of where Salvo fits a Colorless deck.

Pick or Skip: Salvo

Across 1276 offers Salvo has a 0.5% pick rate; the 6 runs that took it and 1202 that left it are still below the sample floor, so no win rate is shown.

Taken 6 times out of 1276 offers.

A win rate is only shown once that side clears the sample floor. Below it you get the run counts and nothing else — a 0% here would be a reporting artefact, not a result.

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.
