Planet is Sephiria's summon tag: rather than dealing damage through your own swing, you summon a planet that orbits and fires projectiles at enemies by itself. It is the most relaxing high-damage style in the game once it is online — you set the summon up, then concentrate on dodging and positioning while the planet does the work.
The archetype's centrepiece is Dark Planet (Legend Planet), which summons a dark planet that fires Chaos bullets, dealing +50/60/70/80/90/100 damage as it levels. What makes it powerful is that it is autonomous: it keeps attacking on a cycle while you are free to move, so your damage does not stop the moment you stop swinging.
Planet builds scale differently from weapon builds. Instead of raising your own attack stats, you raise the summon's: Planet Attack Speed, projectile count and size, and how quickly your own attacks cycle the planet's next shot. The better you understand that the planet is a separate damage engine, the better the build performs.
Choosing Your Planet
Every planet is a different flavour of companion damage, and which one anchors your run usually depends on what drops. Dark Planet is the damage ceiling, firing Chaos bullets for up to +100. But the tag has options for every element:
Sky Blue Planet fires lightning laser beams for up to +60; White Planet fires ice bullets up to +72; Red Planet launches fire missiles up to +60; Ashen, Blue and Yellow planets offer physical and bouncing-projectile variants at lower numbers.
Treat the first strong planet you find as your anchor and build around it — chasing a specific colour usually wastes the early chapters.
- Dark Planet — Legend. Chaos bullets up to +100 damage. The top summon.
- White Planet — Rare. Ice bullets up to +72 — strong single colour.
- Sky Blue Planet — Advanced. Lightning lasers up to +60.
- Red Planet — Advanced. Fire missiles up to +60.
Scaling the Summon
Two items define how a planet build ramps. Giant Telescope (Rare Planet) adds +5/10/15% Planet Attack Speed and enlarges the planets sitting within your 8 inventory slots — larger planets fire bigger projectiles that deal +50% more damage. It rewards holding your planet items in the board's active slots rather than scattered.
Sheet Music 'Galaxy' (Rare Planet) turns your own aggression into summon speed: it grants Attack Speed, and every Weapon Attack you land speeds up the planet's attack cycle. This is the key to the archetype — you do not stand still and let the planet do everything; you keep attacking to make the planet attack faster.
Because the planet is companion-style damage, watch for general companion scaling too. The storm-cloud item Flux Coupler Mk.2 even triggers an extra Storm Cloud when a companion deals Lightning damage, if you decide to blend elements.
- Giant Telescope — Rare Planet. +5/10/15% Planet Attack Speed and enlarges planets in your slots for +50% damage.
- Sheet Music 'Galaxy' — Rare Planet. Attack Speed plus every Weapon Attack speeds up the planet's attack cycle.
- Flux Coupler Mk.2 — Rare Storm Cloud. Activates an extra Storm Cloud when a companion deals Lightning damage (for hybrids).
How to Play It
Early, get a planet up and learn its range. Remember the planet follows you, so your positioning controls where its projectiles go — staying near the enemy keeps the summon in range.
Mid-run, build the double loop: your Weapon Attacks accelerate the planet's cycle (via Sheet Music 'Galaxy'), and the planet keeps damaging even during your dodges. Place planet items inside your 8 active slots so Giant Telescope enlarges them.
Late, you get the relaxed payoff. Kite and dodge while the enlarged planet shreds the boss. The build is excellent for learning boss patterns hands-free, because a large share of your DPS comes without you committing to a risky swing.
Blending With Other Summons
Planet is a clean core that coexists well with the other autonomous-damage tags. Blend Storm Cloud and let Flux Coupler Mk.2 fire extra lightning whenever your planet deals it; or add a little Mystic for global Universal Damage Boost that also raises your planet. The through-line is that all these systems reward you keeping them active while you focus on survival.
Frequently Asked Questions
Does the planet inherit my True Damage? There is no evidence in the item data that flat True Damage carries onto companion projectiles. Scale the summon with Planet Attack Speed, Planet size and Universal Damage Boost instead of chasing True Damage for it.
Which is better, one strong planet or several weak ones? Generally one strong, well-scaled anchor beats several unleveled ones, because Giant Telescope and count items reward concentrating on a slot. Enlarge one great planet over spreading thin.
Do I stop attacking once the planet is up? No. Sheet Music 'Galaxy' makes your own Weapon Attacks speed up the planet's cycle, so you should keep fighting to keep the summon firing faster.
