By this line of reasoning you don’t gain more HP for a higher CON when it increases, because you cannot change your favored class bonus.

I'm not sure these two situations are the same. The rules for ability scores explicitly state that changes to CON modifier retroactively increase or decrease HP.

If a character's Constitution score changes enough to alter his or her Constitution modifier, the character's hit points also increase or decrease accordingly.

The whole problem is the Dark Secrets text does explicitly state whether a change in CHA modifier or oracle level affect the number of Dark Secrets spells available to the caster. Maybe it should and this is errata, or (possibly more likely) I've interpreted it wrong.

What he’s arguing it that he believes it does not scale with level and stat changes. That if you take it at first you only ever get 1 bonus spell, and if you took it at 19th you’d get up to 9 (19/2=9.5 rounded down). Nothing about his post says anything in regards to it being taken multiple times.

Yes. Apologies for being unclear.

I guess really my question is whether the revelation scales with oracle level after you take it. If an 18 CHA oracle takes Dark Secrets at first level, RAW they can add one shadow/darkness spell to their list of spells known. Everyone seems to assume that at 4th level, that same oracle would suddenly gain access to a second shadow/darkness "slot", because their [oracle level/2, rounded up] is suddenly higher than 1.

Two things make me wonder whether this is the case. Firstly, the description doesn't say that's how it works. All the description says is that -- at the time of taking the revelation? -- you can add X amount of spells limited by your CHA and oracle level. Further, the description does mention a (limited, different) form of level scaling:

Each time you gain an oracle level after taking this revelation, you can choose to replace one of these spells for a new appropriate spell on the sorcerer/wizard spell list.

Why would it scale twice? Additionally, there is this from the base oracle description:

Unlike other divine spellcasters, an oracle's selection of spells is extremely limited.

If the whole point of the oracle class is they have a small spell selection to compensate for being 2/3rds BAB + ~full divine casters, it seems odd this feat would give them access to that many more spells.

For context: I'm a newbie and it's totally possible I've misread everything here. In fact if that's the case I'll be glad because it makes my level 4 shadow oracle a lot more powerful. Appreciate everyone's responses so far.

Sorry for the bump but I've also wondered about this.

Oracles can effectively take Dark Secrets at any odd level. Assuming the upper limit of "half your oracle level" rounds down, Dark Secrets gives a minimum of 1 extra shadow/darkness spell at level 1, and a maximum of 9 extra shadow/darkness spells known at level 19.

The description allows for one (1) shadow or darkness spell to be replaced (i.e. not added) at each oracle level up:

Each time you gain an oracle level after taking this revelation, you can choose to replace one of these spells for a new appropriate spell on the sorcerer/wizard spell list.

RAW it would seem that no increase in CHA shifts that initial allotment. An oracle who takes Dark Secrets at 3rd level will always have 1 slot available for darkness/shadow spells; an oracle who takes Dark Secrets at 11th level will always have 5 slots available for darkness/shadow spells.

IMO this makes Dark Secrets a waste of a revelation or feat prior to 5th level.
