Lance Beam is a legendary major card out of the New mechanic pool. Aether Beam reaches 16 u as a thin lance at 135% damage, but you stand still while channelling.

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 Prism and Flood Beam. Take one and the rest are gone for the run.
