The Light Guardian was ready to fight, to do whatever it took to defend the road to the castle, but the forces between him and Adam were not equal.
The further the Phantoms and monsters went down the evolutionary path, the more the outcome of the battle was affected by even a small difference in strength.
Adam didn't need any of his powerful abilities to deal with such a large, powerful foe. Just like the Light Guardian, he only needed a few swings of his hammer to kill a dozen serpents.
Adam was not yet strong enough to easily fight S5 monsters, but the S4 monsters were no match for him.
Only Arnoth and Kreyna could give him trouble, especially Arnoth.

Adam landed, the great guardian's body crumbling to the ground behind him with a clatter.
'Arnoth...' Adam muttered internally, raising his gaze towards the castle. 'I don't know if you're looking at me right now, but I can feel your aura. It's quiet, almost nonexistent, but I was able to uncover it.'
