Sam stood and studied the fights. Measha needed just one more little push and victory would be assured, thought Sam.
He pondered and stared at the old man and his control over the goo. The stuff seemed useful for just about anything.. Let's put that to the test shall we?
Sam broke off a sharp icicle and dipped it in the vial. Meanwhile he sprinted to the other side of the battlefield, taking care to not get caught in the crossfire.
A few meters and a few more close calls further and he'd found himself behind Axcel. He scooped up some of the guild master's blood and with his finger he drew a sigil of chaos on the shard.

[i]"Fire and Ice, powerful magic unknown and blood of the anarchist... And an invitation for magic to flow freely." [/i]
Sam mumbled to himself as he concentrated on the spell.

He took a piece of cloth from the wreckage and wrapped the cold weapon in it, so it only showed the very tip of the icicle.
After finding eye contact with Measha he tossed it over carefully, accompanied with a foreboding look. Making it clear that this was a dangerous tool. Sam silently gestured a stabbing motion, followed by a thrust of his open palm, as if throwing a fireball, then jumping back and covering his face with his arms. That should be clear enough he thought.
