Classes or Abilities that focus on SLA's?

[CyberThread]

Besides feats, if you have SLA's what sort of classes or PRC's can you use to enhance them or expand the use of them?

[The Mentalist]

I think that's mostly an area for Feats actually, though Archmage and Heirophant give you new SLAs.

Warlocks are all SLA based aren't they? I was pretty sure Invocations were considered SLAs but I'm not looking at the book now to be sure.

While the above is true, they are not "true" sla's due to needing gestures and all that fun stuff so has limitations that normal SLA's do not.

If you take the magic mantle, psionic manifesting classes do. Otherwise, manifesting powers is a psi-like ability, but they're very similar.

Warlocks and DFI use specialized SLAs, called invocations. While they have Somatic components, even that is questionable.

Phrenic (http://www.d20srd.org/srd/psionic/monsters/phrenicCreature.htm) and Half Fey (http://www.wizards.com/default.asp?x=dnd/sp/20040213a) get enough SLAs to be classes by themselves.

If you take the magic mantle, psionic manifesting classes do. Otherwise, manifesting powers is a psi-like ability, but they're very similar.

Which is very, very confusing. The rules for psionics were obviously written by this guy, who holds the real powers:

Which is very, very confusing.Not if you actually pay attention, but I'm tired of trying to explain it to you, since you obviously don't.

I am still trying to figure out where the reals powers are, and why the author felt the need to make it the case in the first place. I already agreed to their behavior.
