Dragonspawn template can be added to any corporeal giant, humanoid or monstrous humanoid of Small, Medium or Large size (hereafter known as the “base creature”). Creature type changes to dragon, with the augmented subtype and the same subtype as the dragon type (fire, cold, etc) of its creator. Size remains unchanged.
Armor Class:+7 natural armor
Attacks: Gains Bite and Claw natural weapons that do (1d4 + Str for medium creature) damage. However, If he mixes the bite attack in with the double scimitar attacks I believe the bite attack takes a -5 penalty as if it was a secondary natural attack so the attack bonus on the character sheet should be +18 not +23. I only suggest this because he didn't list the Claw attacks at all so it looks like he is mixing in the Bite attack with the double scimitar attacks.
Breath Weapon (Su): is usable every 2d4 rounds
Spellcasting (Su): Gain ability to cast as 1st level sorcerers (if sorcerer already add +1 caster level)
Special Qualities: All of the base creature plus
Low Light Vision
Darkvision 30'

Abilities: STR+8, DEX+2, CON+6, INT+2, WIS+2, CHA+4 (Red)
Feats: as base creature + access to draconic feats
Alignment: Same as dragon creator (I don't know what campaign world this is in but normally this would require a CE alignment)
Level Adjustment: +4 (Red)
