"If an attack deals less damage than you still have as temporary hit points from force ward, it still reduces those temporary hit points but otherwise counts as a miss for the purpose of abilities that trigger on a hit or a miss."
I am confused by the wording on this. Does that mean no on-hit effects happen if the ward is there? What about touch attacks? Ranged or Melee? Whether they do damage or not? Such as ray of enfeeblement. Since it is not getting through the barrier. Also, does personal DR apply to the temp hit points? Such as having an geokineticist with DR 4/Adamantine at lvl 8 and then takes the expanded defense aether.
As the force ward is a physical barrier, it only effects physical attacks, therefore, a ray is unaffected. As for DR I would say that the DR applies to the damage that bypasses the Force Ward and not before it affects it.
