Some questions about items:
If I used a multi target move (namely Rock Slide) and am holding blunder policy, do I have to miss one target or all targets for it to activate?
If I'm holding throat spray and use a sound move into protect, does it still activate? What if it fails (say, due to no target)?
Does utility umbrella just provide protection from sandstorm/hail damage, or does it also reduce damage from weather boosted attacks. If Eiscue holds a utility umbrella does ice face still regenerate? Similar question about swift swim and other weather abusers.
Multi target moves will activate blunder policy so long as one target is missed
Throat spray will only activate if the Sound based move hits the target. Failing and connecting into protect does not activate the item
Utility umbrella protects users from effects. In sandstorm and hail they will take the weather damage.
In the case of Rain, Which water type moves are boosted, the target will receive non-boosted damage thus retaining the original damage it does not affect move accuracy (Thunder and Hurricane) as far as I could tell. Using thunder in the rain with the umbrella seems go to 100% accuracy (Or I could be lucky, I'm still testing it.)
Unsure if this affects healing moves such as Synthesis or Solar beam (These moves get boosted in harsh sunlight). I don't have a pokemon to test this yet.
Unsure if this affects abilities like Eisue's. Other abilities like swift swim seem unaffected. My lvl 45 Ludicolo was faster then a lvl 60 Bisharp with the rain set up (Will test out Dry skin at some point)
