White Skin
Despite all of the MC cells that Sil had, even with them combined with his strongest abilities, nothing seemed to be able to harm the thick white skin of the celestial. It was the first time for Sil, even when he was fighting against other celestials, that his skills couldn't do something.
However, despite this, perhaps he was being too cautious in the fight, because it took Borden to act, before Sil began to realize that he was nowhere near done. He hadn't even touched the tip of the iceberg in comparison to what he could do.
The first thing Sil did was clone himself, twelve different times to be exact. As he did, each one of them opened up a portal and pulled out demon tier level weapons. Swords, spears, shields, and of course Sil himself was also using his favorite demon tier weapon, the trusty trident.
'If I can't hurt him with abilities and such, I can always just use weapons and my natural strength.' Sil thought.
