After Duke mastered the White Mist Forest Potion, he naturally no longer needed to stay in this laboratory.
He is much freer than other wizards; although he doesn't receive monthly bonuses, he can freely choose any potion to refine.
Duke plans to refine the Echoing Whisper Potion afterward, a potion that can temporarily increase one's Spiritual Power.
The Echoing Whisper Potion is also in great demand and is quite popular among wizards.
Generally, a single Echoing Whisper Potion can boost Spiritual Power by over ten points, although the specific value depends on the user's current Spiritual Power.
With a single Echoing Whisper Potion, Duke can enhance his Spiritual Power by roughly twelve points, lasting eight to ten hours.
Wizards researching spells, refining potions, or conducting experiments often need a temporary boost in Spiritual Power to better complete those tasks.
