"Figured out when it's useful to use the Heavy Ball in USUM (spoilers for 'mon availability)"

Pretty much what it says in the title - here's a list of Pokemon you can encounter in Ultra Sun/Ultra Moon that actually are easier to catch with the Heavy Ball than with a standard Ultra Ball. Spoiler alert - most of these are legendaries. I've also provided the effective multiplicative modifier for each 'mon, so that you can decide whether other niche balls would be better for certain situations.GeneralSnorlax - x2.2 (only encountered through SOS battles)Regirock - x7.67Registeel - x7.67Giratina - x11Cobalion - x7.67Terrakion - x7.67Kyurem - x11Zygarde - x11 (as long as it's in 50% or Complete forms - which it should be, unless I'm very mistaken)Ultra Sun ExclusiveGroudon - x11Dialga - x11Heatran - x11Reshiram - x11Ultra Moon ExclusiveLugia - x7.67Kyogre - x11Palkia - x11Regigigas - x11Zekrom - x11Edit: As a reverse to this post, here's a list of stuff that CANNOT be caught in the Heavy Ball in Sun/Moon. Be safe, don't go windmill-tilting.Edit2: Turns out the Heavy Ball uncatchables in SuMo have had their Heavy Ball catch rate boosted to 1 in USUM. Soooo... disregard previous edit pls. via /r/pokemon http://ift.tt/2i8WlTK
