The hidden Aspect of Supay grants the Devil Sparks and enhances your Rush Boon, rewarding a mobile, sprint-heavy fireball build.
The Aspect of Supay is the Umbral Flames hidden aspect, leaning into mobility by granting the Devil Sparks and boosting your Rush Boon.
The Umbral Flames already play as a kiting weapon, and Supay doubles down on that by rewarding your Sprint. The Devil Sparks ride your movement, and the aspect raises your Rush Boon damage, the boon attached to your Sprint, up to plus 45 percent at the top rank.
It is the build for players who want to never stop moving, weaving fireballs and a powered-up sprint together into a constant-motion playstyle.
This guide covers how the Devil Sparks and Rush Boon work, how to reveal the hidden aspect, the rank scaling, the best build, and when to pick it over the other Umbral Flames aspects.
grants the Devil Sparks and enhances your Rush Boon.
a strong Rush Boon and mobility that keeps you sprinting.The Aspect of Supay grants the Devil Sparks and enhances your Rush Boon, tying the Umbral Flames damage to constant movement.
On the Umbral Flames, you already fire fireballs while moving, which makes the weapon a natural kiting tool. Supay rewards that motion further: the Devil Sparks come with your Sprint, and the aspect raises the damage of your Rush Boon, the Sprint-slot boon you draft from a god.
The wiki tracks the aspect by Rush Boon Damage, so the build is about pairing it with a strong Sprint boon and then never standing still. You sprint to reposition, leave Devil Sparks behind, and keep the fireballs flowing the whole time.
Draft a Rush Boon as early as you can. Supay only enhances your Sprint-slot boon, so a run without one leaves the aspect's main scaling unused; prioritize a god's Sprint boon and the Devil Sparks do the rest.
Supay is a hidden aspect, so it must be revealed through a ritual before you can buy it.
Per the wiki, unlock both the Aspect of Moros and the Aspect of Eos on the Umbral Flames and go out one night with each, then upgrade either aspect to rank 5. Talk to Moros with any weapon equipped until he gives his waking phrase, then activate the Silver Pool in the Crossroads to reveal Supay.
Because it gates behind owning and leveling two other aspects, Supay is a later unlock, not an early-run pick, so plan to invest in Moros and Eos first.
Take Moros and Eos out for a night each, push one to rank 5, then talk to Moros every return to the Crossroads. The waking phrase only appears in conversation, so frequent chats are the fastest way to surface it.
The aspect scales Rush Boon Damage, so each rank makes your Sprint-slot boon hit harder.
| Rank | Rush Boon Damage |
|---|---|
| Rank I | +10% |
| Rank II | +15% |
| Rank III | +20% |
| Rank IV | +25% |
| Rank V | +30% |
| Rank VI | +45% |
Ranks II through V each cost Nightmare, and the rank VI jump to plus 45 percent unlocks through the Hephaestus Legendary boon Premium Service. The bonus only applies when you have a Rush Boon equipped, so the value of ranking Supay up is tied directly to how central your Sprint boon is to the build.
Higher ranks only pay off with a strong Rush Boon. If your run cannot find a good Sprint boon, the aspect's scaling sits idle, so weigh Supay against the other aspects based on whether your build leans on Sprint at all.
The strongest Supay build pairs a powerful Rush Boon with constant movement so the Devil Sparks and Sprint damage stay active.
Draft a strong Sprint-slot boon, then support it with mobility and boons that reward kiting. Keep firing fireballs while you reposition, and use the Sprint as both an escape and a damage tool rather than only a dodge.

Apollo or Hestia (damage on the fireball stream)
Magick regen sources (sustain Omega Moves)
Aphrodite Weak (safety while kiting)
Hephaestus blast (area on the fireballs)In practice this build is pure motion: sprint through a pack leaving Devil Sparks, fire fireballs the whole time, and let the enhanced Rush Boon punish anything you pass. Across multiple runs, Supay rewards aggressive, mobile play more than any other Umbral Flames aspect.
The Supay build wants a strong Rush Boon, mobility, and fireball damage that works while you move.
Any god Sprint boon feeds the aspect, so draft the best Rush Boon on offer and let Supay amplify it. Apollo and Hestia add damage and burn to the fireballs you fire while sprinting, keeping your personal output high.
Zeus lightning rides each fireball and chains across packs, Aphrodite Weak keeps the foes you pass softened, and Hephaestus blast widens your area. In practice, the Rush Boon choice defines the build and everything else supports the kiting.")
Treat Sprint as offense, not just escape. Supay turns your Rush Boon into a damage source, so the strongest players sprint through enemies to deal damage rather than only sprinting away from them.
Pick Supay for a mobile Sprint build, and pick a different aspect for a turret, a combo, or crit.
The Aspect of Eos drops a Daybreaker turret for low-effort area damage, and the Aspect of Moros adds a lingering-and-detonate combo. 
The Aspect of Melinoe gives the fireballs a chance to crit as the simplest scaling path.
Supay is the niche mobility pick, best when your run has a strong Rush Boon and you want to play in constant motion. For most builds the Eos turret is the stronger default, but Supay shines for sprint-focused players who already lean on their Sprint boon. The full Umbral Flames weapon guide compares all four aspects in depth.
On the Umbral Flames, the hidden Aspect of Supay grants the Devil Sparks and enhances your Rush Boon, the Sprint-slot boon you draft from a god. The aspect scales Rush Boon Damage up to plus 45 percent at rank VI, rewarding a mobile, sprint-heavy build.
Reveal it by unlocking the Aspect of Moros and Aspect of Eos on the Umbral Flames and going out a night with each, upgrading one to rank 5, talking to Moros until he gives his waking phrase, then activating the Silver Pool at the Crossroads.
The Aspect of Supay is the hidden aspect of the Umbral Flames, Ygnium. It builds on the weapon's kiting style by granting the Devil Sparks and boosting your Rush Boon, turning constant movement into a damage source.
The Rush Boon is the Sprint-slot boon you draft from an Olympian, attached to Melinoe's Sprint. The Aspect of Supay scales its damage, so the aspect only reaches its full value when you have a strong Rush Boon equipped.
Draft the strongest Rush Boon you can, then support it with mobility and fireball damage like Apollo or Hestia. Keep Magick up for Omega Moves, take Aphrodite Weak for safety, and play in constant motion to keep the Devil Sparks and Sprint damage active.
It is strong for sprint-focused builds with a good Rush Boon, but its value depends on finding one. Without a strong Sprint boon, the aspect's main scaling sits idle. For most runs the Aspect of Eos turret is the safer, higher-floor pick.
Pick Supay for a mobile Sprint build when you have a strong Rush Boon, and pick Eos for a low-effort Daybreaker turret that works in any run. Eos is the higher-floor default; Supay is the niche payoff for sprint-heavy play.
Rank VI gives plus 45 percent Rush Boon Damage, but the bonus only applies with a Rush Boon equipped. Rank it up if your build leans on Sprint, and weigh it against other aspects if your runs rarely take a strong Sprint boon.
