Rewards

Preparation

You may use up to 3 squads and 1 item set for this battle. Each of the squads must have unique units in them and you are allowed up to double your total cost. You select a different friend from your entire friends list for each squad that you can bring in. There is no cooldown when using a friend to fight Karl. Your items do not get replenished when a team dies, so bring as many healing items, elemental seals, and status cure items for paralysis/weakness as you can for this fight.

Overview

It is highly recommended to have units that are at least 5★ rarity. A Thunder team is also recommended if you are using 5★ units.

This is a rather old trial, so units at higher rarities will be able to have a much easier time clearing this trial, even without much effort.
