The Agony Bomb is the Mythic, top-tier bomb in Mine a Mountain. It costs $600,000,000 cash plus 1499 Robux, has the largest blast radius in the game at 28, and leaves a signature crater shaped like a rift. It exists to open the highest-value ore veins: it is the bomb required to break Dreadstone veins, and community gameplay describes it as tearing the mountain open and dropping only legendary and mythic crystals. Before you commit to one, two caveats are worth keeping in mind: no authoritative return-on-investment numbers exist, and whether Dreadstone veins even spawn in your mountain depends on its shape.
What is the Agony Bomb?
The Agony Bomb is the Mythic tier of bomb in Mine a Mountain, sitting at the very top of the eight-bomb ladder added in the July 3, 2026 update. It is the most expensive bomb in the Bombs Shop and the strongest, with the widest blast radius of any bomb. Like the other seven, it is bought at the Bombs Shop at spawn, and the shop restocks on the same hourly cycle as the mountain.
There is no official Agony Bomb page from the developer: the official Roblox game page does not mention the Agony Bomb, so the stats below come from the community wiki and are best treated as community-verified rather than developer-confirmed.
Agony Bomb stats
| Stat | Value |
|---|---|
| Rarity / tier | Mythic (highest tier) |
| Price | $600,000,000 cash + 1499 Robux |
| Blast radius | 28 |
| Crater shape | Rift |
The Agony Bomb’s cash price matches across the Fandom wiki and the sportskeeda snippet, while the Robux component and the blast radius come from the Fandom Bombs table. The radius of 28 is the largest of the eight bombs; the next widest is the Thunder Bomb at 24.
Why the Agony Bomb matters
The two reasons players chase the Agony Bomb are Dreadstone veins and the high-tier drops it opens.
Dreadstone veins. The Agony Bomb is the required bomb to break Dreadstone veins. Per the Fandom Veins page, Dreadstone ore spawns at roughly 75% or more of the mountain’s total height and needs to be buried at least 60 studs below the surface to form. Because a bomb only breaks material at its own tier or lower, the Mythic Agony Bomb is the only bomb that can open Dreadstone. This is a single specialized source, the Fandom Veins page, so treat the exact numbers as medium evidence rather than a hard rule, and re-check them against the current game version.
Legendary and mythic drops. Community gameplay is the main evidence here. In the video guide, the creator describes using the Agony Bomb and pulling huge mythic and legendary crystals from the blast, so many that they filled an 11-ton backpack. The phrasing “drops only legendary and mythic crystals” reflects that gameplay description rather than an official statement, so attribute it to the community rather than to the developer. One note from the same source: the bombs themselves do not boost your luck — luck only applies while mining — so the Agony Bomb is a way to crack open more of the good stuff, not a way to roll better odds on what you find.
How the bomb tier rule works
Every bomb in Mine a Mountain follows the same rule: it can only break vein material at its own tier or lower, and no higher. A bomb that is strong enough destroys the vein and drops crystals from that ore’s exclusive pool; a bomb that is too weak bounces off and drops nothing, so you waste it.
The ladder runs Classic, Wind, Ice, Fire, Thunder, Poison, Time, then Agony at the top. That is why the Agony Bomb matters: as the Mythic tier it can break anything in the game, while every bomb below it leaves the higher veins untouched. It is also why the bombs trick page treats matching bomb to vein as the real skill rather than simply buying the most expensive bomb you can afford.
The crater: a rift with Aetherstone and Cracked Lava
The Agony Bomb leaves a signature crater shaped like a rift, in the same way the Time Bomb leaves a sundial, the Thunder Bomb a forked mark, and the Poison Bomb an acid basin. That crater shape is what players use to recognise an Agony Bomb blast before they dig in.
The crater also lines with valuable terrain. Per the Fandom Aetherstone page, an Agony Bomb crater contains both Aetherstone and Cracked Lava, while a Thunder Bomb crater contains Aetherstone only partially. Aetherstone, also known as Purple Magma, is a diggable terrain material that requires a Mythic pickaxe to break and drops no crystals below Epic tier. This crater claim comes from a single Fandom page, so treat it as medium evidence and check the current version before relying on it. See the Aetherstone page for more on which bombs leave it behind.
Is the Agony Bomb worth the price?
There is no authoritative answer, and that matters: we have not found any measured return-on-investment figure for the Agony Bomb from the developer or an official source. A fan community site offers a Bomb ROI calculator as an auxiliary tool, but that is a fan tool, not an official number, so we cannot point to a reliable profit figure for this page.
Our own take, which is opinion rather than a game rule: the Agony Bomb is genuinely the strongest bomb and the only one that can open Dreadstone veins, so if collecting Dreadstone or the highest crystals is your goal, you have no substitute. But its price is the highest in the game, and its value depends heavily on whether your current mountain actually spawned any Dreadstone. On a tall but thin mountain, the summit may not be thick enough to hold a vein that needs 60 studs of depth, and such a mountain can generate zero Dreadstone. If you buy an Agony Bomb and your mountain has no Dreadstone to crack, you are paying the top price for a large-rift crater and high-tier crystals that a cheaper bomb might partly deliver.
What is still unconfirmed
The Agony Bomb is recent content — it arrived with the bombs update on July 3, 2026 — so prices, values, and effects can shift with any patch. Anything flagged here should be verified against the current version before you rely on it.
- The exact Dreadstone spawn conditions come from a single Fandom page (medium evidence), and some mountain shapes may generate zero Dreadstone, so “guaranteed Dreadstone” claims are questionable.
- The sportskeeda guide ranked the Agony Bomb as the top-tier bomb but was blocked by Cloudflare during research, so only its search snippet was available; treat any ranking from it as weak.
- The official Roblox game page does not mention the Agony Bomb, so nothing on this page is developer-confirmed.
- There is no authoritative ROI number, which is why the “worth it” answer above is framed as opinion.
You can compare the Agony Bomb against the other seven bombs and prices on the bombs trick page, and see what a Mythic pickaxe and Boulders drop for the vein tiers around it.
