Aberrant Dragonmark Mystery
( Player's Guide to Eberron, p. 49)[General]
You can use the power of your aberrant mark to enhance your magical abilities.
Prerequisite
Concentration 6 ranks, Aberrant Dragonmark,
Benefit
When you cast a spell, imbue an infusion, manifest a psionic power (see Expanded Psionics Handbook), or use a warlock invocation (see Complete Arcane), you can sacrifice a daily use of the spell-like ability granted by your aberrant dragonmark as a free action to increase the caster level of the spell, infusion, power, or invocation by +1.
