Mob loot without laggy mob farms – calculated, not farmed.
Requires Super Cool Calculator (SCC) 1.5.0+ – this is an add-on and does nothing on its own.
Study a creature by hunting it. Imprint its form into a Specimen Core. Let a Simulation Calculator replay the fight inside a glowing star-glass orb.
Every cycle rolls the mob's real loot – including Looting, "killed by a player" and the drops other mods add on death – and sends it straight into your SCC storage.
No spawners. No kill chambers. No entities piling up. No lag.


- Hunt – carry a Stellar Bestiary while you fight. Every kill teaches you more about that mob.
- Imprint – right-click a living mob with an empty Specimen Core. The mob stays unharmed; the core now holds its form and shows it as a tiny hologram.
- Simulate – put the core into a Simulation Calculator on your SCC cable. It draws power from the network, takes Stardust Matrix from storage and puts the loot back into storage – visible in every SCC terminal.


Every mob in your pack – automatically
There is no fixed mob list. When the server starts (and after every /reload), Calculated Mobs scans every living entity and its loot tables – modded mobs included.
Add a mod to your pack and its mobs are there. No datapack, no config.
And the loot is not a copied list: every cycle rolls the real death drop:
- the loot table
- drops a mob creates in code (yes, the Wither's Nether Star)
- its equipment
- the drop events of other mods (Apotheosis gems, Immersive Engineering shader bags and similar)

Your knowledge of each mob grows through six stages. The higher the stage, the more often a simulation succeeds:
- Basic – 25 % success
- Red Dwarf – 45 %
- Yellow Star – 65 %
- Blue Giant – 80 %
- Neutron Star – 92 %
- Singularity – 100 %, and a 25 % chance that a cycle keeps its matrix
Successful simulations teach a little on their own, but only up to Yellow Star – beyond that, only real hunting counts.
Research Dial: slide it from Loot to Research in the calculator window and every successful cycle teaches more – up to three times as much, all the way to Singularity – while less loot comes out (none at 100 %). With SCC: Calculated Defense installed, a Specimen Core in a Star Tower turns the tower's kills of that mob into hunting knowledge.
The Stellar Bestiary
The Bestiary shows every mob of your pack:
- a rotatable, zoomable model
- your knowledge as a constellation
- the loot with chances at Looting 0 and III
- the yield per cycle for every stage
- where the mob lives – dimensions, biomes, structures
Filter by mod, bosses only, or learned/unlearned.




The Simulation Calculator climbs the same star tiers as SCC and is upgraded with the normal SCC tier upgrades:
- Basic – 1 core, 15 s per cycle
- Red Dwarf – 2 cores, 12 s, Looting up to I
- Yellow Star – 3 cores, 9 s, Looting II, 2 parallel
- Blue Giant – 4 cores, 6 s, Looting III, 2 parallel
- Neutron Star – 6 cores, 4 s, Looting III, 3 parallel, bosses
- Singularity – 8 cores, 2 s, Looting IV, 4 parallel, bosses
Upgrades – up to 4 each, forged in the SCC Star Forge:
- Pulsar Accelerator – each one cuts the cycle time by 20 %
- Plunder Lens – +1 Looting each, capped by the tier
- Binary Star Splitter – one more parallel simulation per core, capped by the tier
Bosses
Wither, Ender Dragon, Elder Guardian, Warden – and modded bosses tagged c:bosses – can be simulated too.
They need a Neutron Star calculator and Blue Giant knowledge, cost far more energy and 16 matrix per cycle. The orb turns into a violet storm with a rune ring and lightning arcs.


- Power from the network, Stardust Matrix from storage, loot into storage.
- Click an empty matrix or upgrade slot to fetch it from storage – or to open the SCC order window. Ctrl+click orders right away.
- Autocrafting: every drop becomes a recipe the SCC planner understands – "Ender Pearl via Calculated Mobs: Enderman". Put a Processing Calculator in front of a Simulation Calculator in On order mode: it runs exactly the ordered amount, then stops and returns the leftover matrix.
- No network? The calculator has its own energy buffer and works with hoppers and pipes.

It looks like it belongs
The Simulation Calculator wears SCC's Star Forge style:
- a steel pedestal with pillars in the tier colour
- a pulsing star-glass orb with the mobs as holograms inside
- a beam of light with a spiral for every finished cycle, and loot that flies along the cable
The window shows the orb as a big hologram, progress rings per core, glass tubes for energy and matrix, a live loot feed and a status line that always says what is going on – in every SCC design (F7).
Quiet sounds, a JEI category and its own chapter in the SCC guide.


Calculated Mobs works with whatever mobs your pack has, because it reads the game's own data instead of a list. Tested with large packs (All the Mods 10, All the Mods 10 To the Sky, FTB Evolution 2), for example:
- Twilight Forest – Naga, Lich, Hydra and the other bosses, including loot that the mod normally drops into a chest
- Ice and Fire – fire, ice and lightning dragons as bosses, with the loot you harvest from their corpse
- The Aether, Cataclysm, Occultism, Deeper and Darker, Aquaculture and many more

Progression stays intact: dungeon keys (Aether), dragon eggs, boss trophies and tower keys (Twilight Forest), the Strange Key (Cataclysm) and Occultism soul shards never come out of a simulation. Packs can add more with the item tag scc_mobs:no_loot or block mobs with scc_mobs:no_simulation.
For pack makers
Everything is configurable in scc_mobs-server.toml: cycle times, energy, matrix costs, knowledge thresholds and success chances, boss rules, block lists for mobs and items, extra loot tables and recipe export.
Commands: /scc_mobs scan, /scc_mobs list, /scc_mobs info, /scc_mobs knowledge.
