Weapon and Armor Proficiency: Dragonmark heirs gain no proficiency with any weapon or armor.
Advancement: At every level of dragonmark heir the caster level of your Dragonmarked bloodline's Least Power increases by 1 (after halving), to a maximum of your character level. This may allow you to access higher-level spells. For instance, a rogue 5/dragonmark heir 3 with the Eldritch Heritage feat would have a caster level of 3 from his character levels (8-2, halved), +3 from this ability for a total of CL6. Such a character could access 3rd-level SLAs from his bloodline.
Dragonmark Mastery: At 1st level you may cast your dragonmark's 1st-level spell without expending uses of its bloodline power (i.e. you may use it an unlimited number of times per day). At every odd level thereafter this ability also applies to spells of one level higher.
House Status (Ex): A dragonmark heir adds half their class level as a bonus on Charisma-based checks when interacting with members of their dragonmarked house (round up).
Improved Dragonmark: At every even level you gain an extra use of your Dragonmarked bloodline's Least Power per day.
Talent: At every even level you gain a rogue talent, or a talent from one other class in which you have levels (eg. a barbarian rage power or an alchemist discovery). Your dragonmark heir levels stack with levels in that class for prererequisites based on class level. Alternatively, you may increase your caster level and spells per day as if you had gained a level in a spellcasting class to which you belonged before entering dragonmark heir.
