Cobweb

Sure Cobwebs are an annoyance in forests teeming with Spiders.
But imagine a forest full of Gargantua Spiders, where getting caught in their sticky silks becomes a matter of life and death!

Cobwebs don't look very strong from afar, but if you go all willy-nilly into places with a lot of them you may find yourself suddenly getting caught up, with a bunch of hungry eight-legged critters watching you and waiting to pounce.
