The first decision is whether the copy in front of you is worth SS resources. Cyclone9's Psyber has no trait and no mutations, so he evolves at S and saves purple plates for a stronger pet later.
Water Guns are the special material tied to the route. Cyclone9 farms Rain Imp on Splash Island and uses 12 Water Guns for each Psyberion evolution attempt.
The recorded route uses fire and ground evolution materials with S-rank Psyber. Cyclone9 fills the extra space with more fire or ground materials and shows the chance reaching about 19.54%, so players should plan for misses.
After missing Psyberion on the first attempt, Cyclone9 uses Gender Swap Potion and breeds the copy once before reverting. That turns a miss into index progress and a chance at better offspring instead of only a wasted roll.
The payoff is a defensive monster. Cyclone9 highlights taunt, 95% damage reduction windows, knockback, and reduced Spire damage taken, which makes Psyberion a serious tank candidate rather than just a new-index entry.
FAQ
Quick answers for the route, materials, upgrades, and next step before opening the full video.
Cyclone9's route uses S-rank Psyber, 12 Water Guns from Rain Imp, and fire/ground evolution materials. The video shows about a 19.54% chance after filling the recipe slots.
Rain Imp is the Splash Island boss introduced in Patch 0.42, and Cyclone9 farms it for Water Guns.
Not always. Cyclone9 evolves at S because his copy has no trait or mutations. Strong traited or mutated copies may justify SS first.
Cyclone9 uses Gender Swap Potion after a missed evolution so the copy can breed as the female parent before reversion, adding index and offspring value.
The video positions Psyberion as especially interesting for Spire because of taunt, damage reduction, knockback, and its Spire damage-taken passive.
