Its standout pairing so far is Arsenal, which lifts its win rate by +29.2% when the two share a deck. On the relic side, Tungsten Rod is its standout companion, worth a +25.9% win-rate swing alongside it. It costs 0 energy, gets upgraded 23.4% of the time, and tends to be picked up near floor 11.

Its most common run-ender is Knowledge Demon Boss, finishing 5.6% of the runs it shows up in.

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.
