Item
Spider Resin
Escape becomes a negotiation with the ground
Primary ingredient: The adhesive gland of a true Cavern Weaver. Temporary summons and Polymorph forms leave no harvestable gland.
This ampoule contains a resin derived from the gland. Throwing it is a general action of 1 tick. It covers a 5 ft space within 30 ft. A creature in that space makes a Reflex save against DC 18.
On a failure, its feet stick to the ground. It cannot move but can otherwise act normally. Breaking free requires a general action and an effort whose chance the GM sets according to Strength, tools, and the surface. The resin has 20 HP, no DR, and burns away in one tick when exposed to flame. A success lets the creature leave the space before it hardens.
Outside combat, the resin can seal a door, secure a rope, jam a mechanism, or glue an object to a surface. It remains hard for one hour, then becomes brittle.
