I am not sure how to do the mechanics, there's very little in the Extinction Curse Player's Guide on how to create a trick, but here's the narrative:
Vespera's performance, the "Dance of the Eternal Rose," unfolds amidst masked riggers wielding glaives. Clad in a diaphanous gown, she effortlessly navigates the rhythmic thrusts and arcs of the deadly blades through pirouettes, spins, and graceful poses. The gown transforms into multicolored scarves, twirling around her in a mesmerizing dance, leaving a trail of vibrant silk. Behind a sheet of silk, Vespera disappears only to reappear adorned in armor with a glaive in hand. The dance continues as she parries, dances, and defeats the masked assailants, symbolizing a powerful narrative of beauty, resilience, and strength.
