How to Beat the Stone Guardian - Kena: Bridge of Spirits
You have to immediately throw the bomb at him and while waiting for it to blow, attack the ads.
He always throws the rock if you do it this way.
The bow activates the weak points which are the key for your success.
Because once you destroy one, that part of the body becomes attackable.
Meaning after you destroy a leg's weak point, you can then shoot at it with a rot infused arrow for example.
Now you can attack the hand.
And then head.
You have to keep attacking like this until he hits 50% HP.
He then enters the rage phase, you need to prepare the rot infused arrow to immediately break it.
After a few seconds, the core on his back will open, send the rots on him and finish him off.
