The true final battle is SO worth it, just use the easy ways out on the crystal bosses for a faster way to the ending; just in case you didn't know: Gigas Lich - Bravely Second + elixir on him Orthros - everyone as Swordmaster, autobattle with everyone doing Nothing Ventured Chaugmar - Salvemaker: 2x Fulmen Shards = Pantheon's Wrath anytime to bypass the barrier Rusalka - no real easy way out here
