Thinking of making a character (primarily because I do not recall seeing a naga in a combat role except for the one time in the main comic):
Stuff So Far
Occupation: Fallen Legion Sniper
Code Name: Cottonmouth
Regular Name: Not sure
+Has a way with words, but uses them to ease tensions and show kindness rather than manipulate people for his own purposes (part 1 of the reason for his codename).
+Crossbow Weapon Focus, carries a short sword.
+Earth Affinity used for mobility (climbing/hanging on to stone walls with tail)
+Weak but lasting Numbing/Disorientation Poison (part 2 of the reason for his codename)
+Tactics: Uses earth affinity to get into position and anchor himself into stone walls for good shots. Preferably in poorly lit areas. Tries to get an idea of the coloration of the walls in advance to wear attire that helps him blend in with the color of the wall in addition to being in the shadows. Coats crossbow bolts with his naturally produced poison (partly for the minor disorienting effects, and partly to show mercy).
