Zoological Obsession [Flaw]
You are obsessed with a type of creature and cannot bear seeing one come to harm.
Effect: Choose a type of creature, such as humanoid, dragon, or abberation (Subject to DM approval). You may not deal lethal damage against that type of creature or attempt to harm them in any way (Includes ability damage or drain or any magical effect that does not include "harmless" under its saving throw). If you unintentionally harm one of these creatures, you are shaken for an hour. This effect bypasses fear immunity.

Additionally, if you see a creature of this type die, you take a -2 morale penalty to all attack rolls and saving throws for 24 hours.

I need to figure out better titles... suggestions for this one?
