Final Fantasy XVI With Two Ds Trophy Guide

Last Update: August 24, 2023 10:09 AM


Clive receiving a potion upgrade in Final Fantasy XVI

In this Final Fantasy XVI With Two Ds Trophy Guide we'll outline which four side quests you need to complete to obtain the trophy and maximise your healing potential.

Something you'll immediately find when playing Final Fantasy XVI is just how limited your inventory is. At any point in time, you can only hold a limited number of Potions and Tonics meant to assist you in battle. Not only is there a way to increase their size and potency, but by reaching the maximum amount of upgrades you'll earn the Final Fantasy XVI With Two Ds Trophy.

There are four upgrades that will be required in order to obtain this Trophy. You'll need to upgrade the potency of your potions twice and upgrade the carrying capacity twice.
