Witch's hex

Witch: Can I use the evil eye hex more than once on a target?

Yes. As long as you apply a different penalty with each use of the hex (AC, ability checks, attack rolls, saving throws, or skill checks), you can have multiple penalties on the same target. Applying the same hex penalty to a target just resets the duration to the most recent use of the hex.

Example: On round 1, you hex the target's AC. On round 2, you hex the target's attack rolls, so the target now has two evil eye hexes on it. On round 3, you hex the target's saving throws, so it now has three evil eye hexes on it. On round 4, you hex its AC again, resetting the duration of the AC-hex (which does not add an additional –2 penalty to its AC). The same thing would happen if two witches were using evil eye on the same target--as long as each evil eye hex applied a penalty to a different thing, they'd all apply.

This doesn't violate the general rule for stacking penalties--each evil eye effect is basically a different source, even though they stem from the evil eye hex (the evil eye hex is much like 5 separate weak hexes under a common umbrella). In the same way that multiple castings of bestow curse on the same target should stack as long as they do different things (penalize Strength, penalize Dex, penalize attack rolls, take no action, and so on), multiple uses of the evil eye hex stack as long as they're targeting different game statistics.

Reach and Objects: Can you pick up or manipulate an object in a square within your reach? Does this provoke an AOO? Does it provoke even if the foe can reach the object, but not your space?

The rules are a little hazy here, but to put it simply, you can affect objects and creatures within your reach. When picking up or manipulating objects, you generally provoke an attack of opportunity, but only against foes that can reach your space. You do not provoke attacks of opportunity from foes that cannot reach you, no matter what action you are taking, even if it includes reaching into a threatened space. Although it might seem realistic to allow an attack in such a case, it would make the game far too complicated.

Breath of Life

By the RAW, it would appear that Breath of Life will not save someone who dies from massive damage, as they have not died due to hp loss and massive damage is not a death effect.
