Legendaries don't spawn passively in the world. They arrive through roaming events — a server-wide broadcast names a species and a biome, the first player to reach that biome triggers the spawn, and only that player can catch what shows up.

How a roaming event works

Three broadcasts punctuate every event — keep chat visible:

1. The aura stirs — names the species and biome as the attempt begins. This is your signal to travel.
2. A player enters the biome — names the first player to qualify. If it's you, hold position for the 60-second timer.
3. It appears — names the species and the targeted player when the Pokémon actually spawns.

Who gets it

• Species cooldown: the last 3 species are skipped before they can roll again.
• Player cooldown: the last 2 targeted players are skipped before they're eligible again.
• Undexed priority: players who haven't yet caught the rolled species get priority selection.

Common to every tier

• Level 70, regardless of tier or species.
• Spawn chance after the biome-hold timer resolves: 30%. If it misses, the system rerolls a biome.
• Allowed dimensions: Overworld, Nether, End.

Commands

Tips

• Watch chat. Every stage is broadcast — the difference between a catch and a miss is usually reaction time.
• Pre-position. If you know which biomes a tier favours (see the tables below), camp near one during peak hours.
• Mind time and weather. Most species only roll in a specific time-of-day window, and some need clear/rain/thunder — check /roaming info.
• Bring the right balls. You get one protected window; don't waste it under-equipped.
• Undexed wins ties. If you haven't caught the rolled species, you're prioritised — keep your dex gaps in mind.

Tiers

Roaming events roll a tier first, then a species within that tier. Tier weights bias which class of Pokémon is more likely to appear in any given event:

Paradox and ultra-beast events fire more often per tier-slot than mythicals, even though there are fewer species to choose from. Mythicals are the rarest tier.

Legendary tier

The largest pool. Most Gen 1–9 box legendaries roll here. Per-entry weight controls how often that species is picked once the tier rolls.

Gen 1–2

Gen 3

Gen 4

Gen 5

Gen 6

Gen 7

Galarian birds

Gen 8

Gen 9

Mythical tier

The rarest tier (tier weight 0.5). All entries share the same internal weight of 1.0, so within a mythical event every species rolls equally.

Paradox tier

Four entries. Koraidon and Miraidon roll three times as often as Great Tusk and Iron Bundle.

Ultra-beast tier

Only two of the eleven Ultra Beasts roam — the rest spawn in UltraSpace. Equal weight within the tier.

For the other nine Ultra Beasts and UltraSpace catch mechanics, see Ultra Beasts.

Time of day reference

Roaming uses Cobblemon's named time windows. The exact in-game hour mapping comes from Cobblemon, not server config — these are the rough bands:
