Efreeti Magic doesn't work on yourself?

[karossii]

Efreeti Magic:

Efreeti Magic Some ifrits inherit an efreeti ancestor's ability to magically change a creature's size. They can cast either enlarge person or reduce person (the ifrit chooses when using this ability) once per day as a spell-like ability (caster level equals the ifrit's level). The ifrit can use this ability to affect other ifrits as though they were humanoid creatures. This racial trait replaces the spell-like ability racial trait.

(emphasis mine)

So, RAW, does this mean an Ifrit with Efreeti magic can only enlarge/reduce other Ifrit, but not himself?

[Nefreet]

Exactly.

Where are you quoting from? This is what the PRD says.

Change Size (Sp) Twice per day, an efreeti can magically change a creature's size. This works just like an enlarge person or reduce person spell (the efreeti chooses when using the ability), except that the ability can work on the efreeti. A DC 13 Fortitude save negates the effect. The save DC is Charisma-based. This is the equivalent of a 2nd-level spell.

Edit: never mind. My bleary eyes didn't differentiate ifrit from efreet.

In my original turnover, they could affect any ifrit, even themselves.

It seems the wording was changed a bit in development though, so yes, as written, they can only affect other ifrits (or any humanoid of course).
