Werther was very satisfied with the results of strengthening his Armament Haki.
He looked at his remaining life force. He had around 370,000 left, and below Armament Haki was the option for Observation Haki.

Werther felt a little embarrassed when he saw its level.
His Observation Haki had never been particularly strong, yet it was crucial in battle.
Most of the enemies Werther faced now were either blindingly fast or had bizarre attacks. One careless moment could cost him dearly.
