Corrupt Rot God BOSS Fight Guide - Kena: Bridge of Spirits
He has several weak points which deal damage to him.
You need to destroy three of them, to be sent into another realm.
In phase one, he only really has two. The first one, he attacks with one of his hands.
Right after that, he generally uses his second one, smacking the ground sending the ice wave.
To easily avoid, jump and as you should be on one side of him, you can target his weak points from there.
Occasionally, he can rush attack but you can avoid it the same way as the hand attack.
The third destroyed weak point sends you to another real where you fight regular monsters.
The first area is very easy, there are only simple monsters, and there should be no problem.
In the second one, there is a big guy, who can cause some problems.
First, you will need to kill the other monster.
And then focus on him with dash attack - attack combos.
You can also try to hit his weak points when he prepares to rush/throw his weapon at you.
But generally you can beat him by dash attacking him.
Once you beat him, you can obtain courage points and get sent back.
After that, you need to again destroy three of his weak points as he adds one more attack to his repertoire.
Which is the laser, the best is to shield it as your shield should be able to sustain it.
Otherwise, this phase isn't any different from the previous one.
So after the third one, you again get sent to another realm, which is a jumping puzzle. Speed is the key here.
Now you get back your remaining courage.
In the last phase, the boss doesn't have any weak points.
It's really about avoiding everything and farming courage from ads until.
He casts this; you can interrupt it by sending your rots onto the spears from his back.
He has three spears in his back so you need to wait for this three times.
In the meantime, you need to avoid the already explained attacks and farm courage if you need to.
Once you destroy the thirst spear, the fight will be over.
