Gloom Magic (SP)
A rogue with this talent gains the ability to cast darkness two times per day as a spell-like ability. The darkness created by this ability does not impair the rogue’s vision.
Magical Racial Traits
Spell-like ability: Tieflings can use darkness once per day as a spell-like ability. The caster level for this ability equals the tiefling’s class level.
Emphasis mine. Now my question is, Gloom Magic allows the rogue's vision to not be impaired, but is that only for the 2 uses of Darkness that it grants, or for all uses of Darkness, granted from this talent, the racial ability, or even Street Magician's spells?
The reason I ask is I see 2 possible interpretations of spell-like abilities: they are pooled together and are all 1 ability, thus benefiting from Gloom Magic, or they are separate SLA's that just happen to be the same spell.
