Tesla Coil Attack

Is Tesla Coil good in Slay the Spire 2?

In Slay the Spire 2, Tesla Coil is an uncommon attack from the Defect card pool. Its effect: Deal 3 damage. Trigger all Lightning against the enemy. The data flags it as a weaker pick, settling at D tier — usually one to pass on unless your deck specifically wants it.

Over 595 tracked runs its win rate sits at 14.5%, almost exactly the overall average. It sees niche play, included in only 2.8% of eligible runs. Offer data argues the other way: taken 28.1% of the time it is shown, runs that picked it win 15.7% against 21.6% for runs that passed — a -5.7% pick lift across 459 decided runs. Within Defect runs it’s drafted 13.0% 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 Energy Surge, which lifts its win rate by +20.0% when the two share a deck. On the relic side, Cloak Clasp is its standout companion, worth a +30.0% win-rate swing alongside it. It costs 0 energy, gets upgraded 30.7% of the time, and tends to be picked up near floor 15.

Upgrading the card adds +3 Damage to its stat line. Of the runs that drafted it, 85 ended in victory against 502 deaths and 8 abandons. Its most common run-ender is Knowledge Demon Boss, finishing 7.2% of the runs it shows up in. See the synergies, class split, and threats below for the full picture of where Tesla Coil fits a Defect deck.

Pick or Skip: Tesla Coil

Taken 508 times out of 1805 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.
