Feeling that the acid was not going to abate as quickly as he had hoped, and with the entire group engage din offensive combat Xavier looked at his arm with a mixture of pain and aggravation. He raised a paw to it, pointing a single digit and averting his face. The snap of magic and the hiss of burning skin followed the maneuver, the destructive magic biting deeper into his skin. Luckily the force had cleaned away most of that pesky vitriolic goo. Unluckily, without some serious healing he was going to be managing the rest of the fight one-armed.
As the others began executing their strategies and counter-moves against the beast, he stripped his coat from his bad arm and quickly began tying the limb up in a way that would prevent it from moving as much as possible. Watching intently...

The magical shield in front of Silas exploded into a fine mist, but it had served its purpose. The momentum of the beast's swipe had been stopped almost entirely, giving Silas a clear window to act.
The Hound whirled in a circle, attacks coming at it from several directions at once. Something was jabbing it in the stomach. Not painfully, hardly even enough for it to feel, but that meant somehow something had gotten beneath it without getting trampled. It was spinning around as much in hopes of stepping on whatever pest was down there as to orient itself to the attacks, for truthfully none so far had harmed it.
It heard more than felt the arrows clicking off of the back of its head, and turned to look over its shoulders. A particularly heavy 'clunk' sounded near the lower part of its face, and then it was reeling. The beast staggered several steps away from the explosion that had rocked its face, the chitinous plates and much of its skin having been blasted free, exposing a black and res mottled flesh. A large portion of the right side of the creatures head was now entirely unprotected, and though its eye was stung by the smoke and debris, it could still see.
It roared and wheeled again, facing back the way it had come from, confronting this dangerous assailant and keeping its face turned away from the rest of the adventurers. Before it knew what was happening its face was forced down into the ground, something heavy and pointed coming down on its neck with tremendous force. One of the armor plates along its backside cracked audibly, splintering like brittle bone beneath the force of that attack. The concussion of the creature being forced to the ground caused a ring of dust to kick up from the forest floor, the shockwave a breeze that blew leaves and dirt across battlefield.
Strong as it was, the blow did not fell the creature, which rose back up again almost immediately. However, it moved with a sluggishness that denoted pain, now both the base of its neck and side of its face exposed to harm. It bucked and twisted, trying to throw the assailants from its back, mouth open hungrily as it growled in savage frustration. Single-minded in its desire to rend and tear whatever living creatures were near it. It was then that Camille's magic hit it in the flank, the semi-solid energy sticking it to the ground. At first it pulled free with a wrenching motion, but the magical energies stuck to it began weighing it down, until soon enough it could hardly move its front leg on the left side.
Feeling the desperate situation it suddenly found itself in, the creature howled. The cry was answered from several spots elsewhere in the forest. It's tongue slipped from its mouth, long and rope-like, lashing around its back to try and catch or dislodge Mort and Neshar, coated in that horrific acid.

Seeing the group in action Xavier was suddenly much more hopeful for their odds. He finished tying off the makeshift sling for his arm. It was time to rejoin the fight... and from the sounds of the howling there was still quite a fight to be had.
