Selene and Hexes

Selene the Moon and her Hexes, the Magick cost to charge them, the Path of Stars upgrade tree, the Moon Beam Keepsake, and how a Hex fits a run.

Selene, the Moon Incarnate, is the source of Hexes: ultimate-style abilities that sit on top of your boon build and fire when you have charged them. She appears during runs to offer you a Hex, and over a run she keeps offering rewards that deepen the one you chose. Hexes are not a passive status like a god’s boon; they are a big, deliberate button you save for the right moment, and learning which Hex suits your build and when to press it is a layer of play on its own.

How Hexes charge

Each night Selene offers three Hexes and you pick one. A Hex charges by spending Magick, the same resource that powers your Omega moves, and when it is ready a crescent-moon icon appears over Melinoë to tell you it can fire. This creates a tension in every run: Magick spent charging the Hex is Magick not spent on Omega Attacks, so you decide how much of your bar goes toward steady Omega damage versus building up to one large Hex payoff. Because Magick refills on entering each room, you can often charge a Hex over the course of clearing a room and have it ready for the next fight.

Example Hexes

The Hexes on offer vary in cost and effect, from defensive crowd control to heavy single-target damage.

HexEffectMagick cost
Phase ShiftSlows everything by 80 percent for 5 seconds150
Lunar RayA beam dealing up to roughly 1,200 damage over 3 seconds120
Twilight CurseA seeking projectile that morphs what it hits140

These figures are the cost to charge the Hex and a sense of its payoff; exact numbers shift with balance patches, so treat them as the shape of each Hex rather than fixed values. The point is that some Hexes are panic buttons, like Phase Shift buying you time when an arena gets crowded, and some are finishers, like Lunar Ray dumping a large chunk of damage into a boss.

Choose the Hex that covers your build’s weakness, not the one with the biggest number. A burst build that already kills fast wants Phase Shift to survive the moments it cannot, while a build that struggles to focus down a boss wants Lunar Ray. The right Hex is the one that does what your boons do not.

The Path of Stars

After you pick a Hex, further Selene rewards during the run feed the Path of Stars, a small skill tree that upgrades and modifies your chosen Hex. This is how a Hex grows from a single ability into a tailored one: the Path of Stars lets you make it charge faster, hit harder, or change behavior over the course of a run. Because the tree is tied to the Hex you picked that night, committing early lets you invest every later Selene reward into deepening it rather than spreading thin.

The Moon Beam Keepsake

You build a relationship with Selene the same way you do with other characters, by gifting Nectar, which earns the Moon Beam Keepsake. Equipped before a run, the Moon Beam grants a head start of one point on your chosen Hex’s Path of Stars, so your Hex begins the run already partway upgraded. For a build that leans on its Hex as a core part of the plan rather than an occasional button, the Moon Beam is the Keepsake worth slotting.

Where the Hex sits in a build

The Hex is the top layer of a run, above your weapon, your boons, and your Arcana loadout. It does not carry a build on its own; it covers the gap your build leaves, whether that is survival, single-target damage, or crowd control. Combined with the right Olympian, a Hex can also form a Godsent Hex, the Hex equivalent of a Duo Boon, which is where Selene’s abilities tie directly into a god’s theme. Treat the Hex as the closing piece you draft around what the rest of the run already does well.
