In PMU 7, there are many different tutors that teach you moves. Some range from teaching you the moves that you forgot to teaching you special new moves. These tutors also have different items that are required for move relearning and learning.
Mushrooms were introduced in PMU 6. For a brief time, they were removed when transitioning to the new PMU 7. But in early PMU 7, Mushrooms made their return. Mushrooms are the easiest to get out of all the tutor items and are used for the basic move relearning. These items are usually dropped from bosses and can be found on the floor in dungeons.
These are used at the Electivire Move Relearn Shop (Link Shop) and reteach forgotten moves. (Ie: Ninetales would be able to relearn its level moves). Tiny Mushrooms are usually found as a common Boss drop, but some enemies in later dungeons can also drop Tiny Mushrooms.
They are used with "Loomy" - a Breloom - and he teaches you a move that your pre-evolved form would have learned (Ie: Ninetales would be able to learn Vulpix's moves) at a certain level. Big Mushrooms are found in any random dungeon that is harder than Winden Pass (including). They are usually invisible, but they can be found on the ground. They are also a rare boss drop.
Shards are colored fragments of an ancient tool that were introduced in PMU 6. For a long time, it was void in PMU 7 before finally making a comeback. While they have no use on their own, a Bronzong apparently has some use for them, and will trade other services for these objects. Shards are a form of tutor items that can be found in many dungeons as an item invisible on the ground. They teach you Black 2 and White 2 tutor moves in Tanren Village. There are four of them:
These shards can teach you a random Physical move that the Pokémon could learn (Ie: Ninetales learning Iron Tail).
These shards can teach you a random Special move that the Pokémon could learn (Ie: Ninetales learning Dark Pulse).
These shards can teach you a random status move that the Pokémon could learn (Ie: Ninetales leaning Role Play).
These shards can teach you a random tutor move, which means that it will randomly choose between all three; status, physical, and special. (Ie: Ninetales having a chance at learning Dark Pulse, Role Play, or Iron Tail).
Misc. Tutor Items
Heart scales are a valuable item that is desired by a Togetic that lives in both Tanren Village and Winden Town. Togetic will teach you a random Egg move if you give her a Heart Scale. (Ie: Ninetales learning Tail Slap). The Heart Scales can only be found in random dungeons that are higher in difficulty then Winden Pass (including). They are found invisible in the wall.
Electivire can be found in all three regions. Electivire allows the player to remember forgotten moves with a Tiny Mushroom.
Breloom can be found in 2 of the 3 regions, residing in Snowveil and Tanren Village. Breloom teaches your Pokémon previous evolution moves for a Big Mushroom.
Togetic is a tutor that can teach your Pokémon a random Egg move for a Heart Scale. Togetic is located in 2 of the 3 regions; Snowveil and Tanren Village.
Bronzong is the newest tutor that is released. Bronzong lives in Tanren and teaches Pokemon a random Black 2 and White 2 tutor move for a shard that corresponds with the type of the move (see above).
- Electivire used to teach moves for 500 poke, but that was replaced by Tiny Mushrooms.
- Big Mushrooms weren't always used to learn moves prior to evolution.
