As you approach the smoking area, you find the creature is indeed lounging about. It's slumped against a wall, casually grabbing fist fulls of a nearby pile of food and dropping them into its mouth and chewing. The pile of 'food' seems to involve a mix of raw material ore, plant matter, magic crystals, and pieces of the villagers. This village is already lost unfortunately. The creature itself is a massive brute, almost half again as tall as you and twice as wide with arms and legs like trees. The description this rabbit woman gave you is, if anything, understated. On the outside of its joints and limbs, it has large bone protrusions, although it's hard to tell from this range, they seem more like metal or possibly crystal shot through with metal, likely uru.
The thick scales bordering on armored plating she mentioned is mostly across the chest and areas that it needs to have flexible. It's skull is a massive block of spikes, its eyes tiny and inset. Even from here, you can see bits of weight and strengthening magic clinging to it, although it seems to have not been using its hardening magic as much. It's not actively casting, as much like yourself, constantly 'clenching the magic muscle' is a good way to hemorrhage energy. This presents you with a slight advantage. With it eating and unpowered, you'll probably get a good chance to approach it for a first strike. Unfortunately, the area around it is mostly clear so you'll have to approach from the side or behind, where its vitals armor and spikes are thickest... The brief memory of the Jagreen trying to ambush Theresa and how that ended for the beast when it found itself in close combat with someone like this flashes through your mind.
You could discuss this with the rabbit woman... whose name you haven't asked, and what she can do. You've also likely got a few decisions to make on the quality of materials you want to leave behind. With the Wyrven, it was airborne, and dropping it from height nearly the killed thing so Gabby was able to strip it of everything of value. This monstrous brute is likely to go down with a much more tenacious fight, and how much you want to salvage of it is likely going to depend on how you attack.
