| A woven silk bag. Something appears to be moving inside...
Opening this bag will release a number of spiders friendly to your cause. You might need to dust off the cobwebs after, however. |
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.
