Twig blights can root in soil, which they do when living prey are scarce. While rooted, they resemble woody shrubs. When it pulls its roots free of the ground to move, a twig blight's branches twist together to form a humanoid-looking body with a head and limbs.

Twig blights seek out campsites and watering holes, rooting there to set up ambushes for potential victims coming to drink or rest. Huddled together in groups, twig blights blend in with an area's natural vegetation or with piles of debris or firewood.

Given how dry they are, twig blights are particularly susceptible to fire.

Resembling bundles of sticks or dead brush, twig blights easily blend in among deadwood, flotsam, and the wood piles common in many rural settings. Groups of them are often found near river crossings, forgotten wells, or natural campsites, where they ambush those who let down their guard.
