Lightsworn Arms is a rare major card out of the New mechanic pool. Attunement: your Main attack deals Holy damage. One Attunement per input.

A Holy Main plants Brands with every attack, storing charge that bursts to help the whole team. The support-friendly attunement — pair it with healing power, and later Release for bigger bursts.

You can take it once · it only turns up when your Main ability can actually use it · it can be offered for 11 of the 34 abilities.

It pushes your build toward Holy.

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