Draco Mon Data Pack FAQ

You need Cobblemon. This pack only adds dragon-type creatures and their spawns on top of it. If you also use the Lostmons add-on, you need the alternate compatibility version of Draco Mon instead of the standard one.

It adds the Goodra line (including Hisuian variants), the Salamence line, the Hydreigon line, the Noivern line and Drampa. Each one has its own biome and time-of-day spawn conditions.

Goomy spawns in swamp biomes while it is raining, and also inside underground lush caves. If a swamp seems empty, wait for rain or head down into a lush cave.

Catch a Goomy and raise it to level 40, then feed it mangrove roots to evolve it into a Hisuian Sliggoo. Hisuian variants also spawn naturally in mangrove swamps, especially high up above Y level 80.

Your Goomy must be at least level 40 before the mangrove roots will evolve it. Level it up first and try again.

Yes. Goomy can be picked up and carried on your shoulder while you travel, similar to a shoulder pet.

The Salamence line spawns in mountain biomes. It appears much more often near stony cliffs, so search the rocky, exposed parts of mountains rather than grassy slopes.

Both lines use night spawns in dark oak forests, and Hydreigon also uses night spawns in mountains, so those spots stay empty in daylight. During the day, try dripstone caves for the Hydreigon line or deep caves for the Noivern line.

Drampa spawns very rarely inside villages. Your odds are better at villages located near mountains, so check those repeatedly and be patient.

It's a data pack that adds new creatures and spawn rules to Cobblemon, not a separate system running alongside it. It shouldn't add meaningful load beyond what Cobblemon's normal spawning already does.
