Where to Find Isaac in The Forge?
Finding Isaac is the first step to completing this quest in The Forge Roblox. He’s located in the Forgotten Kingdom, which is the second area you unlock in the game. To reach the Forgotten Kingdom, you need to be at least Level 10 and have completed all quests for Sensei Moro, including the End of the Beginning quest.
Once you’re in the Forgotten Kingdom, head east from the main area and turn right at Greedy Cey’s stall. Follow this path north, then turn left to go east. When you pass through the gate, turn left again before you reach the Wizard’s house. This will take you up a slope to the south where you’ll find a small camp outside the Ruined Cave.
Isaac can be found in a tent on the northern side of this camp. He’s the injured NPC sitting under the same tent as Captain Rowan. Isaac has a distinct appearance with bandages and looks visibly sick. When you approach him, you’ll see he’s in a weakened state and needs your help.
To start the quest, simply talk to Isaac and ask if he’s okay. He’ll explain that he needs a health potion to recover from his sickness. This conversation officially begins the “Cure for Isaac” quest in your quest log.
What Health Potion Does Isaac Need?
This is where most players get stuck in The Forge quest guide. Isaac is very specific about which health potion he needs, and he won’t accept just any potion. Many players make the mistake of buying the wrong type and wasting their gold.
Isaac specifically requests a Health Potion I. He will not accept Health Potion II or any other potion variant. If you try to give him the wrong potion, he’ll respond with “Is this a joke to you?” and refuse to accept it. This is why it’s crucial to buy the exact potion he needs.
To get the correct Health Potion I, you must travel to Stonewake’s Cross. This is the first area in The Forge Roblox where you start the game. You can use the portal in your inventory to teleport back there quickly.
Once you arrive in Stonewake’s Cross, look for Maria’s Potion Shop. It’s located near the central hub area called The Forge. Maria’s shop has a distinctive purple sign with a potion bottle icon, making it easy to spot. The Health Potion I costs 150 gold, so make sure you have enough money before making the trip.
The Health Potion I has a basic appearance compared to other potions in the game. It’s the simplest and least expensive health potion available, which is why Isaac specifically needs this one for his recovery.

Frequently Asked Questions
Where exactly is Isaac located in The Forge?
Isaac is located in the Forgotten Kingdom, which is the second area in The Forge Roblox. To find him, start from the main area in the Forgotten Kingdom and head east. Turn right at Greedy Cey’s stall and follow the path north. Then turn left to go east through the gate, and turn left again before the Wizard’s house. This takes you up a slope to a small camp outside the Ruined Cave. Isaac is sitting under a tent on the northern side of this camp, in the same location as Captain Rowan. Look for the injured NPC with bandages who appears sick and weak.
What happens if I buy the wrong health potion?
If you buy any health potion other than Health Potion I, Isaac will reject it when you try to give it to him. He’ll say “Is this a joke to you?” and the quest won’t progress. Unfortunately, you cannot get a refund for the wrong potion, so you’ll have wasted your money. You’ll need to make another trip to Stonewake’s Cross and spend another 150 gold on the correct Health Potion I. This is why it’s so important to buy the right potion the first time and double-check that you’re getting Health Potion I specifically.
Can I complete Isaac’s quest multiple times?
No, Isaac’s quest is a one-time-only quest in The Forge. Once you complete it successfully, you cannot do it again on the same character. This is why it’s important to complete it correctly the first time and ensure you get all the rewards. The permanent benefits like increased stamina capacity and extra stash storage will remain with your character for the rest of the game, so there’s no need to repeat the quest anyway. Focus on getting it right the first time to maximize your rewards.
Is the Cure for Isaac Badge useful for other quests?
Yes, the Cure for Isaac Badge is quite useful for other quests and interactions in The Forge Roblox. It serves as proof of your helpfulness and unlocks special dialogues with certain NPCs throughout the game. Some characters will react differently to you when they see you wearing the badge, and a few side quests only become available after you’ve obtained it. Make sure to equip the badge when talking to new characters to see if they have any special dialogue options or additional quests for you.
How much stamina do I get from completing Isaac’s quest?
Completing Isaac’s quest gives you a permanent 15% increase to your stamina capacity in The Forge. This might not sound like much at first, but it makes a significant difference in gameplay.

Why does Isaac say “Is this a joke to you?”
Isaac says “Is this a joke to you?” when you try to give him any health potion other than Health Potion I. He specifically needs the basic Health Potion I from Maria’s shop in Stonewake’s Cross to recover from his sickness.
