Mystery Tickets

The community nickname for this whole system is "gachapon" - the game's own flavor text leans into it too ("Sometimes monsters randomly drop gachapons!", and a line describing "a mysterious 'person' in spawn looking for gachapons"). The actual item is called a Mystery Ticket, and this page covers it exclusively. If you were looking for the unrelated item literally named Dye Gachapon, that's a much simpler random-Dye pull with its own entry on the Systems Glossary.

◆Redemption odds - not published anywhere

Neither this site nor the wiki has an exact drop-chance percentage for a Mystery Ticket from any specific monster, or odds for any individual reward inside the pool below. Re-checked directly against the wiki's own Mystery Tickets page while reworking this section: it still states the chance only qualitatively ("the higher a monster's level, the higher the chance"), with no percentages anywhere on the page. That's a real gap, not an oversight - no source anywhere states a number, so none is guessed at here.

Getting one, and redeeming it

Acquisition: every monster in the game has a level-scaled chance to drop a Mystery Ticket - a higher-level monster means better odds, per the wiki - the same shape as virtually every other drop in the game.

Redemption: take it to Spawn Grounds and hand it to the NPC the community and the wiki call The Mysterious Man (the game's own flavor text is vaguer, only ever calling him "a mysterious 'person'"). Each ticket redeems 1:1 for one random pick from the pool below.

The reward pool - 60 items

Categorized exactly as the wiki documents it. Named items are listed individually; where the wiki itself groups several color/recolor variants under one line (extra hat styles, dye-style shards and crystals, potion/food variety) that grouping is kept as-is here rather than guessed apart into individual names this project doesn't actually have.

CosmeticsFireworks (Red, Blue, Yellow), Cat Ears, Wolf Ears, Bandana, Santa Hat, Goggles, and assorted other hats
Gems & SoulsNurturing Gem, Mystic Gem, Calamity Gem, Energetic Soul, Turbulent Soul, Ambitious Soul, Chaotic Soul

Several of the named Souls above (Energetic, Ambitious, Chaotic, Turbulent) are also normal per-kill monster drops in their own right - see the Systems Glossary for that side of things. Energetic and Ambitious Soul additionally double as pet food - see Companion Pets.

♥Named credit

The full 60-item reward pool and its categorization above come from the official community wiki's Mystery Tickets page - this isn't stored client-side in a form this project's own datamined files give access to, so the wiki's own compiled list is the source here. Cross-referenced on the Sources page.
