This Seeking Tech guide will explain how you can beat Klaww without taking any damage in Jak and Daxter (2024) on PS4 and PS5.
Use the following video as a reference to the text:
First Phase
For the first phase, he will throw rocks at you. To safely avoid these, jump to a safe platform. Use the shadows of the rocks to get a better idea of where they will be heading. Try to focus on jumping between two platforms instead of three.
The last rock he throws will have a Blue Eco, so make sure to grab it.
Afterwards, move forward while dodging the rolling rocks. Once you get the yellow eco, shoot it at Klaww until he drops the boulder on his head.
You then need to quickly run back to the beginning of the arena as a giant rolling rock will be chasing you back.
Second Phase
In the second phase, the rocks will be thrown at greater velocity, so make sure you pay more attention when jumping.
Once you grab the blue eco, you will need to move forward again to grab the yellow eco. You will have less platforms to work with, so you may need to make some timely jumps.
Third Phase
For the final phase, the rocks will be coming at you at an even faster rate. Try to stay near the edge in between two rocks to give yourself an extra split second to jump.
Once you grab the blue eco, carefully move forward to grab the yellow eco to shoot at Klaww to end the fight.
