Corrupt Taro Boss Guide - Kena: Bridge of Spirits
Start with hitting the lantern and then shoot as many arrows as possible.
Until he blindly attacks for the second time.
After that, roll towards him and unleash as many melee attacks as possible.
While stunned, try to hit him with arrows, but do not shoot the blue core.
After this, you have to wait for his attack, so his lantern gets replenished.
Then block it and roll away.
You will need to repeat this until he gets to 50% HP.
Then he enters his rage form.
To avoid his first and the most deadly attack, you have to roll and after you hear the 4th slash, activate the shield.
Continue to rot or shooting the bell stun him during this phase.
On your last courage rot stun, break the blue core.
If you don't have that much courage, you will maybe see this attack more than once but it is easy to break.
