Survivor Trophy in Clair Obscur: Expedition 33

Reach level 99.

Bronze trophy

Any one character at level 99 counts. Everything else leaves you around level 90, and the last levels take millions of experience each. Grind before Peace At Last.

In Renoir's Drafts, from the Golden Tree flag, go down the ramp to the building and grapple up the ramp behind the enemies to the Gestral Merchant.
Fight it. It brings two companions. Beating all three without taking damage gives about 2.1 million experience, and you can fight it again straight away.
Hit all three in one turn with Maelle on First Strike and Cheater: shoot the merchant to Burn and Mark it, then use Last Chance to enter Virtuose Stance and Phantom Strike.

Characters outside the fight get half the experience.
