Infested Storerooms

Senior Enchanter Leorah has been in a bad mood all day. Perhaps you can help her out and get a favour in return?

Background
Senior Enchanter Leorah has a spider problem. You need a rod of fire. Time for a bit of quid pro quo. (Note that if you already have a signed request for the rod of fire, Leorah will reward you with some potions.)

Walkthrough
Kill all Giant Spiders in the Tower storerooms and return to Leorah.

Result
Either a signed request form for a rod of fire or some potions.
