Weaknesses
There is little known about the weaknesses of naga, however, given their rarity, it is possible there are some that can kill them. Skinning naga can hurt, but it cannot kill them, as can punctures to their underbelly, the softest part of the body. Piercing of the heart (as with ANY creature or being) is fatal, as is damage to the brain. 
Cold Blooded- as with any reptile, naga do not heat their bodies naturally. They require warm climates and enjoy contact to heat. This means any living in climates that go below a human base-temperature will suffer from sluggish and less active demeanor, and frigid temperatures will cause them to go into deep hibernation (if left for too long, they can die). 

now I have another character in the process of being made if you decide no on the naga.
