3 Part Pathfinder Question

[RogueWizard]

I'm playing an Oracle in a campaign with the time mystery, not that it's super relevant to my questions, but whatever. I have three mostly unrelated questions for pathfinder.

1. Can spells I cast be dismissed by me if they are not designated as dismissible? Example, temporal stasis. A spell with a permanent duration. Is there any rule, feat, metamagic/anything that can make it easier for me to dismiss should I decide I want it to end?

2. In the time mystery there is an ability
"Aging Touch (Su): Your touch ages living creatures and objects. As a melee touch attack, you can deal 1 point of Strength damage for every two oracle levels you possess to living creatures. Against objects or constructs, you can deal 1d6 points of damage per oracle level. If used against an object in another creature’s possession, treat this attack as a sunder combat maneuver. You can use this ability once per day, plus one additional time per day for every five oracle levels you possess."
So for people and small objects how it works is very straight forward, the question is how it works for large objects. For example, let's say I decide to use aging touch on a stone wall, a wooden floor, or insert object that I want to only damage a certain portion of here. How much of said wall would it damage? Would I be able to shape the area, concentrate on a certain section, would it be a cone or a spread? Would it just not work? Would it be purely DMs call? The rules on that are very unclear.

3. Are there spells/magic items that increase saves? In 3.5 I would always use greater resistance, but that seems to not exist in pathfinder. Are there any suitable replacements in pathfinder that anyone knows of?

Thanks for any and all assistance.

1) A spell not listed as Dismissible (D) cannot be dismissed, it stays in effect until its duration runs out. You can, however, end it prematurely through use of Dispel Magic. (https://sites.google.com/site/pathfinderogc/magic/all-spells/d/dispel-magic) "You automatically succeed on your dispel check against any spell that you cast yourself."

2) You can damage large objects with your weird Oracle aging touch just like using a weapon to attack that section of the object. Large objects can have multiple sections (https://sites.google.com/site/pathfinderogc/equipment---final/damaging-objects), each with its own hit point total. So you would most likely have to tunnel through a specific section of a wall.

3) Loads of spells and magic items increase saves. The Cloak of Resistance is an old favourite. There does not yet seem to be a middle-ground Resistance-bonus spell between Resistance (+1) and Protection from Spells (https://sites.google.com/site/pathfinderogc/magic/all-spells/p/protection-from-spells) (+8), but I find the Cloak is a pretty acceptable solution for most circumstances - and probably costs less than running a Protection from Spells long-term.

Heroism, Good Luck, the Protection from Alignment series, and my personal favourite, Channel Vigor (http://www.d20pfsrd.com/magic/all-spells/c/channel-vigor), are all spells that provide bonuses to saves. Many of these bonuses, in fact, are differently named bonuses which stack with your Cloak (recall, like in 3rd ed, bonuses with the same type name do not stack with each other - so you can't have two stacking Resistance bonuses to saves - but bonuses with different names DO stack, you take the highest active bonus from each name type and add them all together).

If you can find yourself a Courageous Weapon (http://www.d20pfsrd.com/magic-items/magic-weapons/magic-weapon-special-abilities/courageous), it will increase all Morale bonuses you have running by 1/2 its Enhancement bonus, which you can use to turn a Heroism spell into a really beefy thing, providing a long-term, fairly large boost to your attack rolls, saves and checks. A Guardian Weapon (http://www.d20pfsrd.com/magic-items/magic-weapons/magic-weapon-special-abilities/guardian), on the other hand, can trade its Enhancement bonus on a one-for-one basis for a bonus to all saves that stacks with everything.
