Sasquatch

Eight feet and change, and it has been avoiding people successfully for a very long time. What it does when it finds a camp is throw stones from beyond the firelight, scream once, and leave - and this works, and the camp moves on, and nobody is hurt. The accounts where somebody is hurt all have the same shape: the party went uphill toward a noise, and there were young ones up there.

Stones From the Dark: 60 ft, save Dex Quick, fail save roll 3d6+3 bludgeoning, cooldown 1 round, thrown from cover it never leaves. It aims to move a camp on and stops the moment the camp starts packing. Fists: bludgeoning, melee 10 ft, +5 to hit, 3d6+3 (two blows), used only when its young are behind it.

Withdraws First: it disengages and leaves rather than fight, every time, unless something is behind it. A party that backs away is never pursued. Nothing to Track: in standing timber it cannot be followed, tracked or brought to bay by anyone, and everyone who has claimed otherwise has come back without it.
