Entomophobia (3.5e Flaw)
From D&D Wiki
An abnormal and persistent fear of insects.
Effect: Whenever an entomophobic character knows(or is convinced) he is in the presence of an insect or insect-like creature (Most spiders, anything normally called a 'bug,' and others at the DM's discretion)he must make a will save (DC 10+number of insects) or be paralyzed until he successfully saves. He may attempt one such save per round. If an entomophobic character attempts to move within one square of an insect or closer when already within 5 ft.(including all melee attack attempts) he must have passed his first will save and successfully make another (DC 15+number of insects, max DC 20). Unarmed attacks made against insects and insect-like creatures suffer a -4 penalty to hit.
A second form of this flaw applies not only to small, crawling things but larger equivalents. Large insect-like creatures (such as Umber Hulks and Giant Wasps) are even more frightening than the smaller ones. The save DC for both circumstances mentioned above is +2 for each size category greater the giant insect is than the ordinary one it is associated with. For instance, an Umber Hulk (resembling a giant beetle) would have a save DC of 20+number of Umber Hulks (beetles are Fine creatures, and Umber Hulks are large which is five categories higher). Saving throws are made separately for insect-like creatures of differing size categories. Characters with this form of the flaw gain +2 to damage rolls made against insects and insect-like creatures with a melee weapon if they can bring themselves to move close enough.
Benefit: Bonus Feat.
