Multi-Cast Skill

Is Multi-Cast good in Slay the Spire 2?

In Slay the Spire 2, Multi-Cast is a rare skill from the Defect card pool. Its effect: Evoke your rightmost Orb X times. The data flags it as a weaker pick, settling at D tier — usually one to pass on unless your deck specifically wants it.

Over 171 tracked runs its win rate sits at 24.1%, 9.8% ahead of the 14.3% all-deck baseline. It sees niche play, included in only 0.6% of eligible runs. Taken 12.8% of the times it is offered, it lands close to neutral on the pick-versus-skip split: 28.8% for runs that took it against 27.3% for runs that passed, a +1.4% pick lift over 125 decided runs. Within Defect runs it’s drafted 2.9% of the time, making it a regular part of that class’s decks. Decks that include it run about 1.1 copies on average.

Its standout pairing so far is Creative AI, which lifts its win rate by +25.5% when the two share a deck. On the relic side, Happy Flower is its standout companion, worth a +30.6% win-rate swing alongside it. It costs X energy, gets upgraded 27.7% of the time, and tends to be picked up near floor 15.

Of the runs that drafted it, 41 ended in victory against 129 deaths and 1 abandons. Its most common run-ender is Kaiser Crab Boss, finishing 9.4% of the runs it shows up in. See the synergies, class split, and threats below for the full picture of where Multi-Cast fits a Defect deck.

Pick or Skip: Multi-Cast

Players take Multi-Cast in 12.8% of the 1000 offers it appears in; those runs win 28.8% against 27.3% for runs that passed, a pick lift of +1.4% over 125 decided runs.

Taken 128 times out of 1000 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.
