Aberrant Dragonmark( Eberron Campaign Setting, p. 47)
Although you are not a recognized member of one of the dragonmarked families, you have manifested a dragonmark.
Dragonmarked race (human, dwarf, elf, gnome, halfling, half-elf, or half-orc),
Lesser Aberrant Dragonmark (Dra) , Dragon Ward (EotLQ) , Dragonmark Luck (EotLQ) ,
This feat provides you with a single dragonmark spell-like ability that is not directly tied to the trueborn dragonmarked houses. All aberrant mark spell-like abilities can be used once per day. When you select this feat, you must choose an aberrant dragonmark spell-like ability from the following list. You can never improve this mark in any way, and you can never gain a second mark. A character with one of the true dragonmarks (least, lesser, or greater) cannot select this feat, and a character with this feat cannot later select one of the true dragonmark feats. A saving throw against your aberrant dragonmark spell-like ability has a DC of 10 + spell level + your Cha modifier. (Spell level for an aberrant dragonmark ability is always 1st.) Your caster level for your aberrant dragonmark spell-like ability is one-half your character level. Aberrant Mark Powers: burning hands, cause fear, charm person, chill touch, detect secret doors, feather fall, inflict light wounds, jump, light, pass without trace, produce flame, shield, Tenser's floating disk. Aberrant dragonmarks are mutations that appear occasionally among the dragonmarked races (usually to those not of a dragonmarked house) that can be traced back to the blood lines of corrupted dragonmarked families eliminated in the War of the Mark. At a quick glance, an aberrant mark could be mistaken for an established dragonmark, but on close inspection its differences are readily apparent.
