So according to Pathfinder Core Rules, Chapter 9, Magic, page 208:
Quote:
The Spell's Result
Bonus Types
Usually, a bonus has a type that indicates how the spell grants the bonus. The important aspect of bonus types is that two bonuses of the same type don't generally stack. With the exception of dodge bonuses, most circumstance bonuses, and racial bonuses, only the better bonus of a given type works (see Combining Magical Effects). The same principle applies to penalties — a character taking two or more penalties of the same type applies only the worst one, although most penalties have no type and thus always stack. Bonuses without a type always stack, unless they are from the same source.
Or in summary, as said in this in

The last sentence of this paragraph references "bonuses" but the sentence before it specifically says "the same principle applies to penalties". This does leave a little room for rules-lawyers to wriggle and squirm and say that only bonuses cannot stack if they're from the same source, but I think the intent of this paragraph is quite clear. Semantically, I would agree that it would have been more clear if the last two sentences were reversed in the order in which they appear, but either way, the meaning is quite clear:
Two or more "typed" penalties of the same type, take the worst one and ignore the rest.
Two or more "untyped" penalties always stack - unless they are from the same source.
But, the first phrase in the Conditional Curse description states that:
Quote:
This spell functions as bestow curse, except that you must state a condition under which the curse is broken, ending its effect.
The thing is I don't know if that "as" in the description means that Conditional Curse "somehow substitutes" Bestow Curse, or it merely intends to explain how it works.
Other than that, Conditional Curse would comply with the rules in order to be stackable with Bestow Curse: A) Untyped penalties B) From different sources.
So, Do they stack or not?
Thanks
