Figure out what it is.

Seth looked at the blade, wondering what exactly it was, considering. It had caused him a deep fundamental agony at a mere scratch, was glowing, and he could feel something warm and fundamentally... positive deep within it.

Thinking for a long moment, looking back to decade plus experience playing fantasy RPGs, he smiled as he came to a eureka moment. This weapon had to have some kind of draining power. It was like one of those weapons that stole hit points from their targets and then used them to hear the welder. That glow was his life ****. The reason it hurt so deeply is because while it basically rolled a 1 for damage, it rolled much better for the drain roll. He was feeling a bit weak. Not badly injured, but fatigued.

Flipping it around he now wondered what to do. He was sure he understood this, but what to do next was still on his mind.

At least besides making a bandage for his hand, he thought before cutting a strip out of the coat and tying it off.
