Death Fly
WARNING: When facing these creatures, it is vital to kill/disable them before they can hit you. With the exclusion of Evolution, who can restore herself by transforming, this creature's default attack will PERMANENTLY lower the target's Strength, with no way of regaining the lost stats.
Evolved from a Shadow Spirit, learning ShadowFlight in the process. It can be evolved into two types, a Magic Level Type that learns Curse or a Support Level Type that learns ShadowBond.
Its skills aren't great, wasting its powerful magic growth, and the rest of its stats aren't all that great either. The only reason to raise one is if you're aiming for a Shadow Fairy but that has a requirement of lust genes 5+, so don't even bother if your Shadow Spirit doesn't have those genes since it's a dead-end evolution otherwise.
