Tatzlwyrm

Short, thick, cat-faced, with two front legs and no back ones, living in the rock crevices above the treeline. The Alpine herdsmen who report it are unromantic people who are describing something that killed a cow. It does not need to bite. Its breath drops livestock where they stand, and it is far quicker over broken rock than a thing that shape has any right to be.

Foul Breath: 15 ft cone, save Con Tough, fail save roll 2d6+3 poison and the target is Weary until it rests, cooldown 2 rounds. Livestock and animals caught in the cone simply drop, no save. Bite: piercing, melee 5 ft, +4 to hit, 2d6+3, used on what has already gone down.

Of the Crevices: it fights beside a crack in the rock and withdraws into it when hurt, and cannot be followed or dug out by anything larger than a badger. Scaled: DR 2, and it presents its armoured back to anything it is not currently biting. It will re-emerge within the hour, from a different crack, having lost nothing.
