>>15529832Though Trick Room and Wonder Room still have -7 priority, Magic Room is buffed to 0 priority, meaning Klefki can Prankster it. It doesn't stop Mega Evolution, though.
If Aegislash is asleep, he can still change stances, even if he cannot successfully use the move due to sleep. I would imagine the same is true of paralysis/freeze but I haven't checked.
Wrapping moves now do double damage with the wrapping.
Critical hits do 1.5x damage, not 2x.
Roar/Whirlwind cannot miss. Ever.
Just like fathers can pass down hidden abilities with dittos, fathers with dittos now have the 80% chance to pass down their normal ability that was once reserved for mothers in past gens.
Fathers can pass down egg moves, which has been reported but people generally don't seem aware that illegal egg move combos no longer exist as a result.
If a Mega Evolution faints and you revive the mon in question, it revives as a non-Mega, and it cannot mega-evolve again.
Egg moves that are overwritten can be relearned at the move reminder. Serebii mentioned this in a discovery thread but never brought it up again.
