There are several ways to obtain them:
With the Pasture Loot mod, you can get certain drops simply by letting Pokémon graze using the Pasture Block. If you’re lucky, they might even leave behind a nice egg for you to collect!
Tip: avoid placing the Pasture Block near cliffs or thorny bushes, as Pokémon can take damage. Also, always fence off the grazing area to keep them safe
For example you can use the Pasture Block to get some Blaze Powder from Charmander line.
Another way to get certain drops relies on your knowledge of the Cobblemon mod:
For example, you can get wool by dyeing Wooloo and Dubwool, then using shears to collect it. Don’t worry, their wool will grow back once they’ve eaten grass.
You can also obtain some drops by defeating wild Pokémon. Check out this drop list to see which Pokémon drop the items you need.
Alternatively, you can buy mob drops from CobbleMerchants inside Department Stores using Pokédollars.
