Guide sections
What to do first
Use these notes as a safe starting route, then check the newest video or codes page for anything that changed.
Collect 16 Vessel of a Thousand Wishes
The Short shows 16 Vessel of a Thousand Wishes as the evolution material requirement. Treat that as the main bottleneck before going to the Pet Evolution booth.
Bring 30 Refined Water Gems
The shown recipe also uses 30 Refined Water Gems. Since Poseidine is a water evolution route, keep Refined Water Gems saved instead of spending them casually.
Use a strong Undine if possible
Cyclone9 recommends using an A-rank or better Undine if you can. The roll is expensive enough that a stronger base copy is usually the better target.
Plan around the 18% Poseidine roll
The Short frames Poseidine as a first-try joke because the shown chance is about 18%. Cinderdine and Telluride are visible miss outcomes, so do not plan as if one attempt is guaranteed.
