Tap Sirius, hold Orion, spend the sky

Sirius hurls a Jade Light scythe that deals Heat and collects pickups on the path. Hold the button to swap into Orion and cast Gravitic Slash instead — a gravity wave that groups and cuts. The hold-swap is the kit, not a menu. Helminth 1 if you are the Roar-Clash config; you lose both line attacks.

Sirius conjures Jade Light motes that regenerate over time. While they orbit, glare cloaks him — a heat-invis window. Attacking launches the motes for Heat damage and status, and you become visible until they regenerate. Hold to swap into Orion and cast Astral Shell, the cosmic hull that is Orion's whole tank plan.

Sirius plants a well of light that heals, can revive allies, and reduces incoming damage. It grows in size and power the longer it lives — Duration is the garden. Hold to swap into Orion and cast Event Horizon, a gravity hole that groups a tile for Slash and Clash follow-ups.

Sirius and Orion rise into a cosmic duel. Each attack spends a Constellation Star for huge collateral (damage type follows the star). Left attack is Sirius, right attack is Orion. Matching the star's color to that brother's paint raises critical chance. Stars come from using 1/2/3 — you cannot slot more than two of the same color in a row. Helminth abilities cannot be cast during Clash; Roar before you take off.
