|Act II - Puerto Valor, Man at the entrance||Metal Slime Shield|
Once you’ve left Sylvando’s troupe with his father at Puerto Valor in Act II, return to town and speak to the old man near the entrance. He asks you to defeat a Knight Aberrant in the Eerie Eyrie with the Arise Pep Power.
It’s best to wait until you obtain more than four party members so you can swap characters who are Pepped Up out. Once you manage to have the Hero, Sylvando and Hendrick all Pepped Up, use the Arise Power against a Knight Aberrant in the Eerie Eyrie before defeating it. Return to the man and report your success to complete the quest.
