Stormbound Focus is a rare major card out of the New mechanic pool. Attunement: your Special deals Storm damage. One Attunement per input.

A storm Special stacks Shock in bursts and sets up Overload discharges for your other hits. Good when the Main serves another element — storm still wants hit volume, so echoing Specials fit best.

You can take it once · it only turns up when your Special ability can actually use it · it can be offered for 12 of the 34 abilities.

It pushes your build toward Storm.

Only one card can reshape that ability this way — this one, or Flamebrand Focus, Rimebound Focus, Venombound Focus, Bloodsworn Focus, Stonebound Focus, Lightsworn Focus and Voidtouched Focus. Take one and the rest are gone for the run.
