Grid bugs are the annoying gnats
. They are creatures of lightning, who shock you over and over with tiny bites. They are the simplest of all monster. Grid bugs tend to be on the first few levels, and have never been seen to leave a corpse. The grid bug death is considered a shameful defeat.
The grid bug has no magic resistance, a speed of 12 (about average) and a AC of 9. They are usually able to be killed in one connecting attack, or one magic spell. They are almost never a formidable foe.
