Tremble Skill

Is Tremble good in Slay the Spire 2?

In Slay the Spire 2, Tremble is a common skill from the Ironclad card pool. Its effect: Apply 3 Vulnerable. The data flags it as a weaker pick, settling at D tier — usually one to pass on unless your deck specifically wants it.

Over 1432 tracked runs its win rate sits at 21.5%, 7.7% ahead of the 13.8% all-deck baseline. It sees niche play, included in only 6.8% of eligible runs. When it is actually offered players take it 24.1% of the time, and that looks correct: those runs win 22.0% against 18.3% for runs that passed, a +3.7% pick lift over 1150 decided runs. Within Ironclad runs it’s drafted 30.5% of the time, making it a regular part of that class’s decks. Decks that include it run about 1.2 copies on average.

Its standout pairing so far is Prolong, which lifts its win rate by +28.9% when the two share a deck. On the relic side, Sai is its standout companion, worth a +36.5% win-rate swing alongside it. It costs 1 energy, gets upgraded 20.9% of the time, and tends to be picked up near floor 12.

Upgrading the card adds +1 Vulnerable to its stat line. Of the runs that drafted it, 303 ended in victory against 1104 deaths and 25 abandons. Its most common run-ender is Test Subject Boss, finishing 6.3% of the runs it shows up in. See the synergies, class split, and threats below for the full picture of where Tremble fits a Ironclad deck.

Taken 1346 times out of 5584 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.
