Aetherstone, also known as Purple Magma, is a terrain material in Mine a Mountain — a type of diggable rock that generates naturally throughout the mountain, separate from ordinary stone. You break it only with a Mythic pickaxe, and it drops no crystals below Epic tier. It also appears as the lining of certain bomb craters: an Agony Bomb crater contains both Aetherstone and Cracked Lava, and a Thunder Bomb crater can contain it in some cases. Everything below comes from a single developer-backed wiki entry, generation rates and drop rates are not published, and the game is in a fast-moving update phase, so treat these details as to be confirmed rather than settled.
What Aetherstone Is
Aetherstone is a terrain material, not an ore vein. The wiki groups “Terrain materials” as its own category of the game’s Mountains content, sitting alongside Veins, Boulders and Crystals — the clearest signal that this is rock you dig through rather than a deposit you crack open. The distinction matters because the two behave differently. Veins are the rare buried ore deposits you break open with bombs; each vein type drops from its own exclusive crystal pool and yields artifacts. Aetherstone instead behaves like terrain: it generates naturally through the mountain, separate from ordinary stone, and is broken with the right pickaxe rather than blown apart like a vein.
There is real room for confusion here. Some players and trading marketplaces treat Aetherstone as a tradeable ore or a radar-detectable resource — a marketplace listing for an “Aetherstone Radar” item is one example — and it is easy to blur those two things. Per the developer-backed wiki, however, Aetherstone is a terrain material, so this page keeps terrain materials and ore veins separate. If you are looking to trade it or to hunt it with a radar tool, that framing comes from community trading sources and is not part of the wiki’s terrain-material description.
How to Break and Mine It
A Mythic pickaxe is required to break Aetherstone. At any tier below Mythic you cannot break it at all. Pickaxes are a tiered item category in the game, and Mythic is one of those rungs — the specific one this terrain material demands. Once broken, Aetherstone drops no crystals below Epic tier — the wiki is explicit that it yields nothing Common, Uncommon, or Rare. Epic is the floor, and everything it drops sits at Epic or above.
That is the extent of the detail available. The wiki does not state how often Aetherstone spawns, how many crystals a single block yields, the ratio of tiers it drops, or what those crystals sell for. So the Epic floor is reported here as a fact from that page, but every surrounding rate and per-tier figure is simply not public. Do not plan your run around a specific crystal count or value, because none is documented.
Where to Find It
Aetherstone appears in two kinds of place. First, it generates naturally throughout the mountain, independently of ordinary rock — which is exactly why the wiki calls it a terrain material rather than an ore embedded in a vein. Second, it forms as the lining of a crater after certain bombs explode.
The wiki names two bombs specifically. An Agony Bomb crater contains both Aetherstone and Cracked Lava. A Thunder Bomb crater contains Aetherstone partially, in some cases rather than always. The wiki does not explain the conditions that decide whether a Thunder Bomb crater lines itself with Aetherstone, so read that as to be confirmed. It also treats “Aetherstone” and “Purple Magma” as the same thing, so whatever name you see in a chat or a guide refers to this same terrain material. For the crater side of this guide see the Agony Bomb page, and for how bombs and their craters work more broadly see the bombs trick page.
What Is Not Confirmed
The honest picture is thin, and the page should be read that way. Aetherstone has no dedicated professional guide and no dedicated video walkthrough; the detail we have comes from a single developer-backed wiki page, so the mechanics here are reported at medium confidence and should be checked against the live game before you plan around them.
Specifically not published or not established: the exact generation rate, the crystal drop rate and tier distribution, per-block yields, and crystal value. Also unconfirmed is how reliably a Thunder Bomb crater lines itself with Aetherstone. And because Mine a Mountain is in a fast-moving update phase, terrain materials can change in any patch — a rule or a value here may be adjusted in a future update without notice. If the game changes, treat this page as outdated until it is re-verified.
In short: Aetherstone is a genuine terrain material in Mine a Mountain, mined with a Mythic pickaxe for Epic-tier or better crystals, and found both naturally throughout the mountain and lining the craters of an Agony Bomb (and only sometimes a Thunder Bomb). Beyond those basics, treat the details here as to be confirmed until you can re-check them against the current version of the game.

Where do you find Aetherstone in Mine a Mountain?
Aetherstone generates independently of normal rock and also lines the craters of certain bombs. An Agony Bomb crater contains both Aetherstone and Cracked Lava, while a Thunder Bomb crater can contain it in some cases. These locations come from a single developer-backed wiki source, so treat them as to be confirmed.
