Vargas nodded, "[color=red]Got it Silver![/color]" he called and took a step further back on the rooftops taking a moment to summon his Eldritch Beast. Then he plunged back into the fray with his companion. First he launched a bolt of magic at the giant creature's knee then as his Hellbolt came of cooldown he tossed that and the creatures foot, tethering it to the ground. The twisted mage that was his companion practically vomited a stream of lava at the monster's other foot. 

The lava splashed all over the foot and onto the ground, if the monster tried taking any steps onto nearby ground it would either land on more lava, have its leg slammed forcibly back into the ground, or most likely both. Hopefully no one was stupid enough to be close enough to the Dissolution's feet to get hit by the lava. Vargas grinned, it looked like everything was going well, then he coughed suddenly and glanced worriedly at his HP bar. It was rapidly dropping, he quickly determined that the gas was rising to his level, a look at his summon revealed that its HP were quickly dwindling even faster than hsi, it was already at nearly 20%, it would only have time for one more spell before it expired. Vargas himself was already backing away as fast as he could, not like he could do much until his CDs were up again.
