In Cobblemon, an IV (Individual Value) is a hidden stat unique to each Pokémon, ranging from 0 to 31 for each of the six base stats, that affects its combat power beyond level and species. A nature is a fixed trait assigned at birth that raises one stat by 10% and lowers another by the same amount. Breeding a “perfect” Pokémon means combining strong parents with the right held items to get a baby with high IVs and the nature suited to its intended combat role.
Cobblemon faithfully replicates this system from the official Pokémon games, using a dedicated breeding block in place of the classic Pokémon Day Care. The logic stays the same: the better the parents’ IVs and the more the right items are equipped, the higher the odds of a well-optimized baby, though nothing is ever 100% guaranteed except for the specific IV locked in by a dedicated item.
What is an IV in Cobblemon
Every Pokémon has six IVs, one per stat (HP, Attack, Defense, Special Attack, Special Defense, Speed), randomly set when it’s generated and never changed afterward (unlike EVs, which grow through training). A 31 IV in a given stat means that Pokémon taps 100% of its genetic potential on that specific stat. A 0 IV in a deliberately weakened stat (typically Speed, in certain battle formats where moving second is an advantage) is sometimes sought out on purpose rather than avoided.
What is a nature
There are 25 natures in the Pokémon system that Cobblemon reproduces, 5 of which are neutral (no effect, like Hardy or Docile) while 20 boost one stat and lower an opposing one. An Adamant nature raises Attack and lowers Special Attack, a Timid nature raises Speed and lowers Attack, and so on. The right nature depends entirely on the role you want the Pokémon to play in combat: a fast physical attacker will look for a nature that boosts Attack or Speed without touching a stat it already relies on.
How to breed a Pokémon with strong IVs and the right nature
- Pick parents with strong IVs. The higher the IVs on both parents (ideally 31) for the stats you care about, the better the odds of passing them on to the baby. A Pokémon earned from a tough trainer battle or caught after several attempts generally has better base IVs than an early random catch.
- Equip the item that locks the nature. A parent holding the item equivalent to the Everstone passes its nature on to the baby at a very high rate, removing most of the randomness from that specific factor.
- Equip the item that improves IV inheritance. An item equivalent to the Destiny Knot, held by either parent, increases the number of IVs directly inherited from a parent instead of rolled randomly, which noticeably speeds up getting an optimized stat spread.
- Hatch the egg and check the baby’s IVs. Once the egg is collected from the breeding block and hatched, the baby’s IVs need to be checked before further training, to decide whether it’s worth keeping or if another breeding cycle is needed.
Tools to check IVs in Cobblemon
Unlike the original handheld games, where a specific character (the Judge in some versions) was needed to learn a Pokémon’s IVs, most Pokémon mods for Minecraft, Cobblemon included, build a screen or command directly into the stats menu that shows a Pokémon’s hidden values. That exact interface point (dedicated button, consumable item, or command) should be verified against the current mod version before writing a definitive step-by-step tutorial.
From theoretical breeding to a real combat stake
A perfect IV stays an abstract stat until it’s tested in a real fight, with something actually on the line. On a PvP server like The Tower, a carefully bred Pokémon can face other trainers under conditions where losing has a real cost: permanent death only strikes inside the Tower and during raid attacks, nowhere else. That turns time spent breeding into a concrete strategic investment rather than a purely collector’s pastime. The server runs a French-speaking beta on Discord, with the full combat rules on the La Tour page.

FAQ
How do you check a Pokémon’s IVs in Cobblemon? Cobblemon includes a screen that displays IVs directly from the Pokémon’s stats menu, without needing a special item or NPC like in some official handheld games. The exact access point (shortcut, button, command) depends on the mod version installed.
Does breeding work the same way as in the official Pokémon games? The core logic is identical (two compatible parents, an item to lock the nature, an item to improve IV inheritance), with a dedicated breeding block replacing the Pokémon Day Care from the handheld games. Egg group compatibility between species is also carried over.
How long does a perfect IV breeding run take? That depends on how many cycles it takes to get a baby with all six IVs at 31 and the desired nature, which can range from a few dozen minutes to several hours of playtime depending on luck and the quality of the starting parents. Using already well-bred parents and the right held items cuts that time down significantly.
