The Ironclad Class

Is The Ironclad good in Slay the Spire 2?

The Ironclad is one of the five playable classes in Slay the Spire 2, starting each run with 80 HP and 99 gold. In the lore and on the table: The last soldier of the Ironclads. Crushes foes with sword and flame against his will. It lands mid-field among the classes, with a 13.8% win rate that’s neither dominant nor weak.

Across 5412 recorded runs it clears the spire 13.8% of the time, right in line with the other classes. A typical run reaches floor 23.8 before it ends. Runs last around 27 minutes and end with roughly 22.6 cards and 8.8 relics in the deck.

Its best-performing card so far is Anointed, at a 71.4% win rate. Close behind is Huddle Up, at a 65.0% win rate. Its best relic so far is History Course, at 84.8%. Its runs average roughly 8 ending HP and reach about ascension 5.3.

That breaks down to 728 victories, 4533 deaths, and 151 abandoned runs. The encounter that ends the most of its runs is Kaiser Crab Boss, responsible for 4.6% of them. Read on for The Ironclad’s best cards, relics, and matchups to build a winning run.

Gold Curve: The Ironclad

By floor 45, The Ironclad runs that went on to win are carrying 460 gold against 190 for runs that died — a 270 gold gap.

• Winning runs 460 gold at floor 45
• Runs that died 190 gold at floor 45

Average gold in hand at each checkpoint floor, comparing {name} runs that went on to win with runs that died. Floors are sampled every fifth map point.

A floor only appears once at least 10 recorded runs reached it, so the chart stops where the data thins out — not where runs end.

Deck Size Curve: The Ironclad

Deck size at floor 45 splits 32.7 cards for winning The Ironclad runs against 32.7 for runs that died.

• Winning runs 32.7 cards at floor 45
• Runs that died 32.7 cards at floor 45

Running deck size at each checkpoint floor — the starting deck plus cards gained, minus cards removed.

Rest Site Choices

Smith is the most-used rest option with 70768 uses and a 21.8% win rate, ahead of Heal on 67331 uses at 19.7%.

Rest-site decisions are recorded across every class, not only The Ironclad, because the choice itself is class-independent.

The bars show how often each option is taken. A win rate is only shown for the options with enough runs behind them — Smith and Heal; everything below them is reported as counts.

Mend is left out entirely: every recorded use of it comes from a co-op run, and co-op runs win far more often for reasons that have nothing to do with the rest choice, so its win rate would be misleading next to the others.

Potion Picks

Potion of Doom carries the best pick lift at +10.8% and is taken in 50.1% of its offers, with Foul Potion next at +9.1%.

Potion offers are recorded across every class. Ranked by pick lift rather than raw win rate.

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.
