Evil Faerie vs Evil Demon

[b-dog]

I was thinking that a useful way to differentiate evil faerie from demons is that faeries are so chaotic and magical that they can not be truly evil and so protection from evil does not function well against them. Also weapons that give bonus attacks against evil creatures don’t do so against evil faeries. This way evil faeries can be used as shock troops against the forces of good while the demonic forces attack the weakened forces of good. Faerie would have vulnerabilities to protection from magic and weapons that affect magical creatures so the forces of good would have to have two different types of weapons.
