Well I am not sure about this but I think that the caster level of spell-like abilities increases by one per HD and that the Spells ability which gives the casting ability of a class would do the same. I can't seem to find a definitive answer in the SRD so my answer is based on the fact that if no caster level is given from a creatures spell-like abilities the caster level is assumed to be the creature's HD. Although neither of these abilities increase in the advanced Lammasu (the only creature with an advanced example and these abilities) so maybe these abilities are fix and never increase due to HD advancement. So in the absence of a difinative rule I would increase them with the creatures increased HD in a way seems fitting to you and is appropriate for the creature's new CR. Sorry I could not be more helpful.Trainz said:I knew that, I didn't ask the right question (moron)...
When a creature is advanced as per the hit-dice advancment rules, at what rate, does his caster-level rises for spells ? A Lillend is a 7 Hit Dice critter, uses spell-like abilities at 10th level, but also casts spells as a 6th level Bard. Using hit-dice advancment, what would his spell-like level and bard level would be like if I advanced the critter to 20 hit dice ?
