A sack of spiders is an evokable item which, when used, generates a Spider's Nest-themed group of friendly monsters, and also generates multiple web traps on hostile monsters in your line of sight. Evocations skill affects both the strength and number of summoned allies, but not the success rate - that is set at 80% regardless of your character's stats and skills. Each sack generates with 5-15 charges, and cannot be recharged in any way.
Potential Results
Each successful use of a sack of spiders is guaranteed to produce at least 1-3 allies, plus an additional 1d(Evocations / 4) - 1.
A table of potential results versus example amounts of Evocations skill:

Strategy
- A sack of spiders is nearly useless without at least 8 or so levels of Evocations. If you haven't put in the training, don't expect any results from this beyond a couple of quickly destroyed meat shields.
- Be careful where you move after using a sack of spiders. Stepping into one of your own generated web traps is a good way to earn yourself YASD.
History
- Prior to 0.19, sacks of spiders didn't stack.
- Prior to 0.18, there were giant mites, spiders and trapdoor spiders summoned if you evocation was still low.
- In 0.15, the webs created when evoking a sack of spiders will target enemies, rather than being placed randomly.
- Sacks of spiders were added in 0.13.
