Modifying SLAs

[Zaq]

So, I have a project I'm working on. For now, I need to know what kinds of feats and class features modify (or can modify) SLAs, regardless of source (so racial, class-granted, or whatever). Here's what I know of right now:

Empower SLA (SRD)
Quicken SLA (SRD)
Boost SLA (BoVD)
Violate SLA (BoVD)
Corrupt SLA (BoVD)
Consecrate SLA (BoED)
Purify SLA (BoED)
Mortalbane (BoVD)
SLA Focus (RoF)
Nosomatic Chirurgeon (Draognmarked)

What others are out there?

Neat, I added it. Thanks.

Magic in the Blood (PGtF)

Sorry, I should clarify: I don't mean that I'm looking both for things that apply to racial SLAs and things that apply to class-based SLAs; I mean that I'm looking for things that apply both to racial SLAs and class-based SLAs.

Primordial Giant template increases the caster level of the character's spell-like abilities by +1. Source is Secrets of Xen'drik and the template requires the creature to have the giant subtype.


*edit*

Shape Soulmeld (Illusion Veil) from Magic of Incarnum gives +1 to the DC of Illusion spells and spell-like abilities. Essentia increases the duration of both also.


Eldritch Corruption from Heroes of Horror says that it applies to SLAs, but then only describes spells in its benefits section (specifics of whether it applies is therefore debatable). Up to three times per day you can, "enlarge, extend, heighten, or widen a spell, as though you had the appropriate metamagic feat" by hurting your ally's Con scores by 2 for each use. It requires Moderate taint.

Complete arcane has maximize SLA, IIRC.

Highly specific, but Races of Faerun has a whole slew of feats for enhancing planetouched SLA's. Eyes of Light, Light to Daylight, Healing Flames, etc.

Probably not quite what you were looking for, but still.

Aren't there SLA 'metamagic' feats in the Tome of Magic? The Shadow Magic section, I think.

Those only apply to mysteries.


Heighten Spell-like Ability (CArc)

The Pathfinder ruling is that SLAs are basically spells, meaning that every bonus and special ability that would apply to spells (such as augment summoning) also apply to the equivalent SLAs. The reason normal metamagic spells don't work is that SLAs don't occupy spell slots and thus can't be cast using a higher level spell slots.

I don't know if this also holds true for D&D, but complete arcane mentions that many feats useful for spellcasters are equally useful for creatures that use SLAs, and that the sudden metamagic feats can be applied to SLAs as well as spells, so I think it's a reasonable interpretation.

Isn't there something in Dungeonscape about how a Factotum can use metamagic on his SLAs? That would only be specific to that class, though.

The Paragon (http://www.d20srd.org/srd/epic/monsters/paragonCreature.htm) template gives a +15(!) CL bonus to SLAs.
