The entry on Aging Touch (Oracle Revelation) says to treat the ability like a Sunder Combat Maneuver.
The Greater Sunder feat allows you to transfer leftover damage from a Sunder maneuver to the wielder.
However Aging touch, effects living things and objects differently. Living things take Strength damage, objects just take damage.
What do you think would happen?
Just imagine the cool effect of touching someone's weapon, turning it to dust and then seconds later the wielder as well.
Interesting. The text says "as a melee touch attack" when using it against a living target. You're not doing that. You're "sundering" an object. And it says to treat it as if it were a Sunder Combat Maneuver.
If by RAW we are to "treat this attack as a sunder combat maneuver", then we should treat it as such...meaning you'd draw an AoO if you didn't have Improved, you gain the bonuses on your attempt from Improved and Greater, and you'd gain the benefit of transferring excess damage to the wielder of that object just as Greater allows.
Makes sense to me as I read this. Maybe someone can chime in with something better, though, as I'm not very fluent with Oracles.
Hmm... The ability is quite unclear as written.
Is it:
A) a touch attack no matter how it is used?
B) a touch attack against living, and a Sunder CMB check against objects?
In my opinion B doesn't really make sense, since it would make it harder to touch an object than a person. That is a bit absurd since a touch attack ignores armor bonus to AC, meaning you just touch that part of the target.
As for combining it with Greater Sunder, I don't really think it makes sense to deal excess damage to the target, since you are simply touching the object.
That aside, I would be inclined to allow it, since it is unproblematic to do so. On average it is 3½ damage per lvl, up to 52.5 at lvl 15. The damage that spill over to the target is minor. If a character makes the feat expenditure, he should get to do this a few per day.
Yes, I imagine the damage would not be that incredible (unless you really push Aging Touch).
However simply swishing away a low level mook with a simple touch should give a nice intimidate bonus :P
As for pushing. If you are a Sylph or an Aasimaar you can use your favored class bonus to basically empower the touch attack (50% more damage) since you are 1,5 times as high in level.
Combined with the wrecker curse (which subtracts your Oracle level from Hardness) you could get to some decent damage numbers and destroy stuff really easy. However you are still limited in uses per day and you destroy loot ^^
Although being an SU ability Hardness probably does not factor in here.
