When increasing ability scores of monsters (by giving them extra racial hit dice, templates or class levels), do you increase the DCs of any spell-like abilities?
In the case of supernatural abilities, such as ghoul fever, the disease states which ability score the DC is based of - clearly indicating that any increase (or decrease) of that ability score affects the DC.
But I'm not entirely sure the same logic applies to spell-like abilities. The monster entry doesn't say which ability score the spell-like is based on (although, I assume it's almost always Cha). I'm looking at the PRD for driders,dryads and mites. Each of those has spell-like abilities with set DCs, and each of those DCs match the formula 10+Cha mod+spell level (if we assume sorcerer/wizard spell level). If these monsters have their Cha increased, does the DCs of their abilities follow?
The saving throw (if any) against a spell-like ability is 10 + the level of the spell the ability resembles or duplicates + the creature’s Charisma modifier.
Yes. Boost cha to boost SLAs.
Thank you

Note that most SU and EX abilities are 10 + ½ HD + Stat, so increasing HD increases DC directly.
