The Third Lamb is the second boss found at the Dome of the Forgotten. It is one of the hardest bosses of the game, with a complicated move list and high damage output. The boss’ attacks are based on physical and lightning damage. He is weak against fire and arcane. Avoid using poison, as that is his strength.

This boss battle has two phases.

During the first phase, he will perform:

• Charged Lightning– The Third Lamb will charge a lightning attack, which will go in an arc in front of him. Keep close to him to avoid being hit.
• Tail stab – The boss will stab you with his tail if you are close to him.
• Slam attack – The boss will slam the ground with his hands, which will cause a small area of knockback damage around his hands. Roll through him to avoid it.
• Strike/Leap attack – The boss will target you with his big hand and leap back. To avoid it, roll away from him.

During the second phase, the boss will become more aggressive and will perform these attacks, besides the previous ones:

• Arc of Lightning – This attack is similar to the charged lightning, though he won’t charge it and the area of effect is way smaller. This attack is quicker, though, and is usually used after the slam attack or the strike/leap attack.
• Jump attack – The boss will jump forward to close its distance to you. Roll through him and attack his back.
• Bite attack – The Third Lamb will bite you with his beak when close to you.
• Lightning ball – The boss will spawn a lightning ball which will break into three arc of lightning which will follow you around.

Some people might have a problem with this boss. Here's a video on how to defeat it.
