Progression

Seven stages, one path

You don't start with magic. A storm and a strange shard wake it. From there every stage is earned: study, ritual, infusion, and finally the confrontation the Hollow has been waiting for.

  2. The AwakeningA storm and a shard
  3. ApprenticeStudy at the Research Table
  4. The Arcane ArtsThe Ritual of the Threshold
  5. MasteryInfuse your first artifact
  6. AscensionThe Ritual of Ascension
  7. ArchmageSilence the Listener

Guided by the Arcane Journal

An in-game book (Patchouli) explains every system as you unlock it: spells, rituals, machines, and the lore of the Circle who crossed the veil before you. Lost Pages found in ruined towers tell the rest.

Magic

Six schools of spellcraft

23 spells across six schools, plus 36 more you can craft from runes. Cast them from a radial spell wheel, powered by your mana. Every spell rises through four tiers, each cheaper and quicker to recharge. Click any spell to see what it does at every tier, what it costs, and how to learn it.

Mana and recharge times are the base values. A Focus Wand, the Arcanist's Hood, wand mastery and server settings can lower them further.

Legendary forms

At Archmage, six signature spells raised to tier IV become legendary. Click one to see what changes.

Combos

Spells remember each other. Shatter: Spark or Void Lance on a creature chilled by Frost Nova deals double damage. Thermal Shock: Firebolt on a chilled creature adds three hearts. Slam: Repel a creature into a wall to stun it for three seconds. Exposed: anything glowing from Reveal takes a quarter more damage from magic.

Craft your own spell

Carve a shape, an element and (if you like) a modifier into Rune Stones, bind them to a Blank Scroll in a crafting grid, and read it. Needs the Arcane Arts.

Rituals, gear & machines

Tools of the trade

Magic in Hollowmancy is something you build up, not just something you cast.

Rituals

Raise an altar and light the circle. Threshold, Ascension, Insight, Cleansing, Deepening, Binding and more, each with its own offering and mana cost.

Familiars

Bind an owl that sees for you, a wisp that refills your mana, or a golem that fights beside you. Two gentler Hollow creatures can be bound too. All grow with time.

Wand mastery

A wand remembers every spell cast through it: Attuned, Resonant, Empowered, Ascendant, Mythic. Each level makes your spells a little cheaper and quicker.

Mana engineering

Store mana in Mana Batteries, carry it through conduits, and let engines work on their own: one coaxes crops to grow, another studies Dull Shards into Knowledge. Infusers fuse items into artifacts, and a Mana Beacon keeps a whole base powered.

  • Infuser and Fusions for artifacts and Hollow Charms
  • Mana Crystals, Batteries, conduits and engines
  • Warding Amulet, Focus Wand and the Archmage's Staff

Beyond the veil: the Hollow

Veil Step tears a door into islands of pale stone adrift in a lightless sky, where ash falls forever. Nothing from the world above lives here. Bring light, and bring a way home.

The Hollow

Ashen islands over the void, with ruined towers and cultist shrines.

The Crystal Barrens

Amethyst spires and humming geodes. Something here is still singing.

The Hollow Grove

Violet moss and crooked glowing trees. The only place that feels almost kind.

The Mirror Sea

A still silver sea where every island hangs reflected beneath the surface.

The Revenant Isle

Morvane's castle, still keeping an oath no one is left to release.

The Depths

Below the islands. Nothing spawns there, and nothing comes back.

Creatures of the Hollow

Nothing from the world above lives here. These do, each rendered from its in-game model. Their remains become Hollow Charms, and builders get crystal lamps, wisp lanterns and Lurker-scale tiles.
