Gold Curve: The Necrobinder

Winning The Necrobinder runs hold 319 gold at floor 45 while runs that died hold 190, a difference of 129.

• Winning runs 319 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 Necrobinder

At floor 45, winning The Necrobinder runs are running 30.9 cards against 30.0 for runs that died.

• Winning runs 30.9 cards at floor 45
• Runs that died 30.0 cards at floor 45

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

Rest Site Choices

Across every recorded rest site, Smith leads on 58240 uses at 21.6%, with Heal next on 57079 uses at 19.3%.

Rest-site decisions are recorded across every class, not only The Necrobinder, 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

Ranked by pick lift, Foul Potion leads at +10.1% with 80.4% of its offers taken, followed by Potion of Doom at +9.7%.

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.
