day 3: a skele-ton of mutts

At first light on the 3rd day, the swamp waters will bubble and stir. From their depths the whites of bones will emerge, plated armor stretched across the rib cages of skeletons. Remnants of old, decayed flesh still dangle from their fingers and jaws, and each wields its own warrior's sword. These skeletons will visit tributes in any area who aren't mandated with other tributes. To defeat them, tributes must attack the pieces that hold them together; the armor.

Good luck.

tl;dr skeleton mutts, 20 HP.
