Oh and since you're all like "using Conjure Living Spell 2/day!" it'd be pretty frigging sweet for you to mention this official means to increasing your none-Racial SLAs per day so I can abuse the heck out of it in meaningful ways.
Dude, it's a racial SLA. Just like how the skill bonuses you get from being a lich are racial skill bonuses.
Unless you're saying that templates don't count as being your race, which I don't think you are - that would be a pretty ludicrous, since you'd have to ignore a shitload of RAW to do so. Just off the top of my head, Races of the Dragon explicitly lists templated creatures as races: "Races presented in this book that have the dragonblood subtype include dragonborn, spellscale, kobold, and draconic creatures." Or, for that matter, the draconic racial class, which says "Upon taking all three levels, you have the half-dragon template, and your level adjustment and ECL are 3 higher than normal for your original race".
90% of my books are like half a continent away (and dndtools is gone), but I think RotD is convincing enough on its own. It's also got a list of races that includes 'half-dragon', too.
But hey if you have any raw that says 'templates aren't races', I'd be glad to see it. I've been away from charop for a while so I'm a bit rusty.
I mean that a Conjure Living Spell living spell only has Ex or Su abilities, and can't actually make another CLS living spell. This is because while it activates the effect of CLS on a hit or an engulf, the ability, once it is part of the living spell, is not a spell or sla, and thus is not available as a target for the effect. Adding an SLA or spell would indeed allow conjuration of living spells of those spells or SLAs, but only on a hit or engulf. What's the duration on the mistling's CLS ability? I found mistling once, but can't find it again.
Lasts for one hour per hit die (quoted it in my post).
So you hand your ooze one of the many magic items that have an at-will spell-like ability, then have it slam to create another ooze, using the at-will SLA to fuel. Or fuse it with a paladin and create a bunch of living detect evils or something.
I suppose you could make an argument that the living spell would, instead of conjuring an ooze from the living spell's power upon hitting the target, drain a use from the target's SLAs and turn THAT into another living spell. Which would just require an intelligent item (or paladin) to be the subject of the ooze's frustration.
Even more arguably, you might say that the living spell has to slam attack an actual spell in order to apply the template... which is weird, but I think still doable.
