Deathgrip vines

Parts of Vor Svetelik have vines that have cracked stone apart. Their stalks are covered in clusters of burrs that fall off and cling to clothing, gear, hair, even skin — annoying, a little painful, but not immediately harmful. Bring those burrs within a few paces of the old sigils of power scattered through the ruins, though, and they rapidly sprout, burrow, grip, and tear. Freeing yourself: roll +STR or +DEX. On a 10+, pick 1 cost; on a 7-9, pick 2; on a 6-, take 1d6 damage (messy, grabby, ignores armor) and the vines keep growing.
