Jak 3: Part 7: The Second Arena Challenge (Wave Concussor & Beam Reflexor)
3King Damas has summoned Jak for another Arena challenge. The Arena is the heart and soul of his kingdom, so he hopes that Jak will prove his worth by continuing to defeat all of his arena adversaries.
----------
You will get the Wave Concussor from Damas after this. It is a Level 2 Red Eco weapon for your Morph Gun that comes after the Scatter Gun. It lets you blast foes with a chargable red ring of death!
You can test this out in your Arena fights, but the game also makes you use one of Dark Jak's original moves.
In Jak 3, you just start out with both the Dark Bomb and the Dark Blast, and even with the change to have Dark Jak can be used in this game, using either one of those two special attacks will drain the entirety of your Dark Eco Meter. You can use them as soon as the meter is bright, but if the meter is dark, then you need more Dark Eco.
----------
After the Arena battle, Pecker picks a fight with Daxter that leads to Daxter giving him a... different kind of bird.
Damas stops the animals and compliments Jak on his skills, or at least he was trying to. He rewards Jak with another Battle Amulet, and he'll need one more to be a Spargus citizen.
----------
You also get the Level 2 Yellow Eco weapon called the Beam Reflexor. It makes the shots of the Blaster ricochet off walls, ceilings, and floors a few times, you can even buy a Secrets upgrade to increase the times these shots bounce. Just know that additional amount is drained every time to shots hit an enemy and keep going.
