The Isaac Quest in The Forge looks like a small task, yet many players fail because they buy the wrong potion. Even though it’s quick to finish, the quest gives valuable rewards if you know exactly what to do. This guide breaks down the location, the correct potion, and the rewards you’ll get after completing it.

Where to Find Isaac & How to Start the Quest
Isaac is located in the Forgotten Kingdom, standing under the same tent as Captain Rowan. If you’ve never been there before, the fastest route is to follow the mountain path that starts near the Greedy Merchant in Town. Keep going until you reach the hidden kingdom area. Once you talk to Isaac, he’ll ask for a specific type of Health Potion, and this is where most players make a mistake.
How to Complete Isaac’s Health Potion Quest
The most common error is buying a random health potion. Isaac only accepts Health Potion 1. Any other potion will be rejected and the quest won’t progress. To finish the quest correctly, follow these steps:
- Use the portal to travel to Stonewake’s Cross
- Enter Maria’s Potion Shop
- Purchase Health Potion Eye for 150
- Do not drink it, keep the potion in your hotbar
- Use the portal again to return to the Forgotten Kingdom
- Talk to Isaac while holding the potion and choose the option to hand it over
Once you give him the correct potion, the mission will automatically complete.
Rewards for Completing Isaac’s Quest
Even though this quest looks simple, the rewards are surprisingly good for early progression:
- A large amount of XP
- Cure for Isaac Badge
- Increased stamina capacity
- Extra stash storage
Only spending 150 makes this one of the most profitable side quests for new players or anyone trying to level up quickly.
Isaac’s quest only works if you buy the correct potion: Health Potion from Maria at Stonewake’s Cross. Follow the portal path, buy the right potion, hand it over, and you’ll walk away with XP, a badge, and permanent upgrades. This is a fast, cheap, and highly useful quest for early progression in The Forge. Keep exploring—many other hidden quests can speed up your character’s growth.
