Phantasm combines Laundry Day and Legionnaires of the Damned to turn one fighter's many equipped metal pieces into a fast, spirit-possessed armor swarm.
Carl builds Bomo's armor from dozens of independently sewn plates and low-quality daggers so every part counts as recently equipped. Donut's Laundry Day removes them simultaneously, blasting metal across the temple and producing foamy bubbles.
Legionnaires of the Damned calls wispy ghosts through a purple rent and places one into each eligible piece. The fragments rise as a loose twin of Bomo, then accelerate into a cutting tornado capable of harming a non-corporeal city boss.
The swarm rapidly drains Asojano's shield while Donut controls it. His green disease blast destroys most pieces, and all metal dissipates when the possession ends, but surviving daggers complete Yemaya's shrine.
Carl expects the system may close the exploit because it converts a single equipped suit into many autonomous weapons.
A buzzing humanoid tornado of separate armor shards and daggers animated by pale ghosts.
Phantasm is the party's engineered anti-spirit boss weapon and remote shrine-manipulation tool.
