Level 64 216 Attack Doryuuzu using Fling against a level 59 126 Defense Burunkeru:
Rugged Helmet: 106, 110, 102, 106, 100, 110, 114, 100, 110, 112, 98, 96, 98, 98, 102, 108, 100, 98, 100, 102
The Smogon damage calculator pegs that at 60 power. No additional effects.
Type-boosting Jewels: Fling fails when the user is holding one of these. Or at least it fails with the ones I tried, which were Dark, Psychic, Grass, Ghost, Ice, Ground, Electric, Steel, Dragon, Normal, Poison, Flying, Fire, Water, and Bug. I don't have a Fighting or Rock Jewel.
Aiming Mark: 18, 18, 20, 18, 20, 20, 18, 18, 22, 20, 20, 20, 18, 18, 18, 20, 18, 18, 18, 22
It doesn't remove immunities when used with Fling; Facade still failed against Burunkeru afterward. This damage range looks like 10 power.
I don't have most of the other new items like Balloon, Bulb, Pressure Band, Red Card (one I'd really like to know the effect of), etc., but I could test the Evolution Stone and Pumice Stone later if nobody else does first. I did check really quickly if Flinging an Evolution Stone to my Poliwhirl would raise its Defense and Special Defense, but it didn't.
