Trial Mode - Stage 1 through 10
Tips on how to complete each of the Stages and a list of the items that can be picked up from treasure chests or stolen from the enemies. Note that you need to have Diamond Armlet equipped in order to obtain the treasure listed. Opening the treasure chest without a Diamond Armlet will result in you receiving consumable and expendable items.
This is an extremely easy battle against six Dire Rat enemies - the same type of enemies that Vaan fights in the Garamsythe Waterway at the beginning of the game. You can also obtain a Diamond Armlet from one of the treasure chests (and this is the easiest way to obtain one).
Just open one of the treasure chests without having a Diamond Armlet equipped which is easy to do if you do not have one yet.
You can make a Ripe Rampager enemy appear in this area if you walk towards the cactus on the ground away from the spawn point.
This stage involves defeating a Nekhbet, Werewolf and four Cockatrice enemies. They are relatively easy to defeat and are weak to Water-element attacks. There is no particular strategy required for this stage.
This battle involves defeating six Bagoly enemies which are just standard foes that you would face in the Nam-Yensa Sandsea or in the Phon Coast. They are weak to Earth Magick.
You can make an optional Imdugud enemy appear if you stand still in the circular area in the center of the zone.
The Lich enemies are weak to Holy-element damage. You can also make a Cultsworn Lich enemy appear if you travel towards the doorway that appears on your right side when you first enter the zone.
The last of the first round of stages involves a repeat battle against the Esper, Belias. You will naturally have to obtain Belias as part of the regular story mode when you complete the Tomb of the King Raithwall.
Make sure not to use Fire Magick or weapons on Belias. Use Aqua Magick if you have it and cast Slow if you are having trouble withstanding its attacks. Use Handkerchiefs to remove the Oil status effect to reduce the amount of damage the Belias does.
