Higrann Reap-Soul Boss

I recommend you to complete the quest when your next task is sleeping, because you will need to sacrifice some of your companions to defeat the boss. 

The Boarserker (Main), Cerry (Second main) and Squire (Option) are good companions to have to defeat the boss, because they give a good damage to the Higrann. A note, make sure you have at least four companions with you! The Higrann is intelligent-type boss, so you are required to have a companion to protect the Boarserker (lowest defense) at anytime.

Strategy:
At the very first round, I used Yraen to protect the Boarserker. Low damages at the first two rounds are expected, because the boss is protected by the shield; do not worry! Proceeding to the second round, I replace the Yraen to Squire to protect the Boarserker. Once the shield is gone, I use hero to protect the Boarserker.

Battling with Higrann Reap-Soul

At some points, you will be in this situation, where all the companions have only one green bar left except the Boarserker. You can either choose to leave the Boarserker unprotected or let the Yraen to die first by protecting the Boarserker. The next companion I would choose to protect Boarserker is Squire.

I believe you could defeat her by using the strategy I mentioned.

Important note: You do not need to exactly follow my strategy to protect the Boarserker, but just making sure that you leave the Cerry as the last companion to protect the Boarserker, and always have at least three strongest companions to tackle the Higrann.

After you defeated the boss, the reaper's key will be given to you to unlock the Higrann's casket. The casket will yield a random ingot (Mostly Bluroc, Domane, Odiemel, etc), Foggy Pearl, random ores, random leather (Mostly good leather), uncut jewelry and purple scarf.

The "Treasures of the reaper" is a repeatable quest, but you need to wait until the cool-down 21:57:00 has passed.
