Shiny Stand skins
SpicyWater describes Shiny Stands as alternate colorations. The Shiny-chance pass changes the skin odds and explicitly includes no Stand or Shiny Stand. [2]
Shiny chance calculation
The 3X Shiny Stand Chance description says it triples the base skin rate before adding the arrow multiplier. It does not publish the base rate or every arrow multiplier, so a final percentage cannot be calculated from this listing alone. [2]
Emote equipment slots
The +2 Emote Slots description raises the total number of equipped emotes to four. It grants slots rather than the emotes themselves. [2]
Demo Bundle archive
The developer marks Demo Bundle as discontinued. Its promised release rewards belong to that historical offer; they are not a current code reward or evidence of a live giveaway. [2]
