Name sack of spiders
Icon Sack of spiders.png
A woven silk bag. Opening it will release a number of spiders and other insects, as well as creating webs nearby. Evocations skill increases its effectiveness. There is a one in three chance of accidentally destroying the sack when using it.

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 in the area. 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.

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.
