Use the Adepti Seeker's Stove to create a portable stove in front of you. Be careful, as it will break if you enter combat near the stove. After creating a stove, the gadget will enter cooldown for 300 seconds. After the cooldown period is over, the Adepti Seeker's Stove will automatically disappear.
Reach Reputation Level 5 in Liyue to obtain the Adepti Seeker's Stove crafting blueprint. It can be forged from the blacksmith in each city.
