This guide shows you how to get the healing spell using the Reservoir key in the game AI Limit. Just know it is available during New Game Plus. If you have a high-speed regeneration of MP, you'll be able to use it quite often since it consumes a lot.

Understanding the Healing Spell

Let's first take a look at the healing spell. You'll notice it consumes a lot—around 60%—but if you regenerate MP quickly, of course, you'll be better off. It provides a perfect amount of healing.

Navigating to the Enemy

To obtain the healing spell, you need to reach a particular area in the game. If you have already done this before, you'll see where it is. If not, follow these steps closely. You'll enter a room where a robot hand shoots lasers. When you first arrive, the robot hand smashes onto the floor.

Defeating the Robot Hand

This machine shoots lasers, and you need to kill it. Focus on eliminating its right hand: you can see its HP bar, so target that until it's gone. Once you destroy the hand, the enemy will fall and will not reappear.

Claiming the Reservoir Key

After the right hand is destroyed, an item appears—it is the key. Below the platform, you can already see the item, but you'll need to jump down to collect it. This is the key to the reservoir.

Unlocking the Reservoir Door

Once you have the reservoir key, continue forward until you arrive at a locked door. Use the key to open it.

Collecting the Healing Item

Beyond the door, you'll encounter an enemy that increases your HP recovery. This enemy is a bit tanky, so you can choose to fight it or avoid it to save time.

After dealing with or bypassing this enemy, you'll see a purple item on the ground—that is the healing spell you're searching for.
