14	Talk to Avad. To finish the quest and secure the support of the Carja, speak to Avad and tell him about the Eclipse.

Tips and Strategies

Maintain Your Distance from Dervahl

Dervahl will come equipped with a Tearblaster. This weapon has limited range so make sure to keep your distance from his sonic attacks.

Note: Getting clipped by a shot will throw Aloy backwards. On top of the damage, Aloy will be left open to attacks due to the long recovery animation.

Kill Dervahl's Men First

Since Dervahl is easy to kite, deal with his men first as they pose a far greater threat during the fight. They mix up attacks between ranged and melee, and will pursue you when you try running away.

Tight areas will limit your range of movement so take the men out of the equation to make the entire fight easier.

Use Fire Arrows on Glinthawks

During the second half of the battle, Glinthawks will arrive en masse. Use Fire Arrows fired from a Carja Hunter Bow or Shadow Hunter Bow to set them alight and get them to land.

Try to keep setting Glinthawks on fire throughout the fight to prevent them from using Frost attacks. When they land after being set on fire, hit them with spear melees to quickly bring them down.
