A benefactor embeds an Escape-Plan-only message warning of Circe's sponsorship and prescribing a secret four-person Magic Missile level-15 setup.
P. Hu signs the concealed text inside Carl's benefactor note. The visible message merely says to save the toraline. When Escape Plan activates, further instructions appear: Circe sponsored Diwata; give Pawna's Cries to Donut; secretly raise Magic Missile to level fifteen using temporary boosts from Prepotente, Imani, and Samantha simultaneously.
If the temporary method fails, Carl may spend his saved Pawna's Tears, which P. Hu promises to replace. The sender's knowledge of both potions and multiple allies' boosts suggests careful outside planning under strict benefactor-message constraints.
P. Hu supplies the warning and exact power-stack required for an undisclosed anti-Diwata countermeasure.
