Beacon is a legendary major card out of the New mechanic pool. Guiding Light mends 3 allies for 4% of max health each press; the bolt is a slow 1.2 u orb at 50% damage.

You can take it once · it only turns up when your Main ability can actually use it · it can be offered for 0 of the 34 abilities.

Only one card can reshape that ability this way — this one, or Twin Lights and Lance of Dawn. Take one and the rest are gone for the run.
