Girantulas, 25'-30' tall beasts with long necks, arachnoid bodies, and dripping fangs, are one of the most terrifying predators in the Mutant Future. They dig earthen burrows near oases and caravan routes, and feast on the hapless travellers and their mounts. Their bites inject a Class 15 poison.
While capable of chasing down even the fastest prey, girantulas prefer to attack from ambush. They cover the landscape around their dens with sticky layers of nigh-invisible webbing, and then emerge when their targets are panicked and sufficiently entangled. Engtangled creatures can't move, but can break loose depending on their STR score. Any being with an effective STR of 18 or less can break free in 2d6 turns, while those with higher scores and/or bladed weapons can break free in 6 rounds...and anyone wielding Vibro or Warp-Field weapons can escape in 1 round. Girantula webs are flammable, and all creatures within flaming webs take 1d8 damage for 4 rounds, after which the survivors are free of the strands.
Girantula lairs are reputed to be littered with valuables...although no one has ever survived being inside one.
