CoroCoro revealed new scans for Pokémon Super Mystery Dungeon, which showcased more information on the role Mega Evolutions will play in the game, as well as new items:
It turns out that Mega Evolutions are capable of breaking through dungeon walls. There are also two new types of items called Lapis and Ringle.
The Ringle is a hold item which can hold various kinds of Lapis inside. Lapis can only be found in dungeons and disappear when you leave the dungeon.
One type is called the “Power Up Lapis,” which increases your Pokémon’s strength and Protect Up reduces damage received and Barrage Protect protects you from multiple hits in a turn.
