M+R: Rayman in the Phantom Show- FINAL BOSS in 1 Turn/1 Turn/1 Turn!

Space Opera Network - Spectral Swing - No Items, Relaxing
Space Opera Network - Burnin' Rock - No Items, Relaxing
Space Opera Network - Operatic Showdown - No Items, Relaxing

Rayman- Must have access to Hook & Glide to reach his areas across all three, although there are multiple options for some of them.

Rabbid Peach- Needs Extra Dash to hit all the lights in Operatic Showdown (and Burnin' Rock, althought there are alt options for that). Starburst needed to power up everyone, and Attack Master with "Critical Hit Chance & Final Hit" to decrease RNG.

Rabbid Mario- Needs Punch Frenzy to damage boss and Selfie to hit the last light bulb on Operatic Showdown + finish the boss if the first three get very low rolls on any battle (this happened in Spectral Swing for me). "Critical Hit Chance & Weapon Damage" decreases RNG.

All three can be done on Average if you're willing to proc a Spark Energy on RM so he can Berzerk (Spectral Swing also needs one on RP so she can glitter), and Demanding is theoretically doable with more spark energy + a POW Block on RP, but I chose Relaxing because it's consistent.

Note: I must disclose that I received an invitation from Ubisoft to attend a workshop and give feedback on Sparks of Hope while it was still in development, and received a copy of this game as a gift.
