Here are some information on the second Echoes of Mana Event – Coffer Chaos.
New Harvest Character
Period: 5/6 6:00 (UTC) – 6/8 5:59 (UTC)
- New ally 4★ Keldric -Guided by the Great Tree- and
- 4★ memory gem “Aim for Wind Acorns” will appear
- You can harvest x1 for 300 spirit crystals, and harvest x10 for only 2,700 spirit crystals! That includes 1 free harvest! If you choose to harvest x10, you’ll get a 3★ or higher ally or memory gem on the 10th harvest!
I believe you can skip this banner if you already own a high level Duran.

Boss Tips
- Easy fight especially if you hit the CP requirement
- Boss will spawn chest at ~60% and ~25% HP. May only spawn chest once
- Boss will start the battle with an AOE move so remember to dodge after hitting once.
- Avoid red things on the floor
- Destroy all the chest to reap maximum reward.
Thoughts: Due to the event being unlimited now, I guess they have nerfed the boss drops for Co-op 🙁
