Aspect of Selene
Sky Fall
Moon Beam powers up the Sky Fall hex; anything that makes Omegas pricier charges it faster.

Six-Hit Dash
Exhaust Riser makes the dash-strike hit six times: perfect for Poseidon or Hestia on attack.
The path
Hera, Poseidon, Hestia or Zeus: the highest rarity between special and attack. Poseidon is the easiest start.
On the other slot: Ares, Zeus, Hestia, Poseidon or Hera.
Good pairs: Poseidon + Ares (Arterial Spray), Hera + Hestia, or anyone with Static Shock.
If Exhaust Riser shows up early, dash-strike liberally.
