(6 + Int modifier per level):Weapon and Armor Proficiency
: Void Dragon Hatchlings are proficient with their natural weapons. They gain no proficiency with shields or armor.
Age Category: Counts as a given age category for true dragon stuff. No, this doesn't let you get epic feats. Looks to be increasing every odd-numbered level has a good feel. If it becomes an issue, it can drop to 1/3 levels.
Breath Weapon: 1d4/level, 1d4 round recharge, cone of nothingness. Often appears as a cloud of darkness, due to it canceling out the light that passes through the area. Range based on size
Claws: 1d4 at Small
Scales: Natural Armor. 1 + 1/odd level. Not worrying at all about how this is ~half what most true dragons get, because this is a class, not a monster.
Invocations: As Nullblade -3 levels
Damage Reduction: DR/magic, more because it's a dragon thing than because it'll necessarily be relevant.
Void Subtype: Gain Void Subtype
True Dragon goodies to add:
Flight speed needs to improve, but maneuverability drop, as size increases.
Improved low-light vision (x4 distance) and darkvision (120').
A couple of SLAs or related abilities
Other potential abilities:
Alternative blinding breath weapon
Nullify, Terminate, and other Nullblade goodies
Banish (temporarily remove someone from existence, as Time Hop)
Void Zone (create an area of nothingness, damages everything within, absorbs light to cause Darkness, etc.)
Void Infusion (delayed save or die of sorts; Fort save or target takes 1d4/round/round of untyped damage until it dies or is destroyed, no duration)
