Are you stuck for time and just don't want to train? Do you need an easy option to raise those levels? It's simple! Kind of. Training is a great thing, it's always worth grinding and battling, but if you really aren't in to that, there is another option for you. It's tricky, but it's well worth your time, it's...Join Avenue! Did you guess correctly? Basically, in Join Avenue, you can open up a lot of stores by talking to visitors who come by, these visitors could be random NPC's or people you met on WiFi, Dream World or through the CGear. When you talk to them, some may want to make a fitness Dojo, and this is exactly what you need to boost those levels! The Dojo can help train your Pokémon up by a level, this costs a lot of money but is worth it. When you recommend more people to your Dojo, it will go up in levels, and you will be able to train your Pokémon up even more levels. By the time your Dojo has reached Level 10, you will be able to train your Pokémon by up to 4 levels each day. You can also still access the options such as raising levels by 1, 2 and 3. Once you have used these options at least once during the day, they will not be able to be accessed until the next day. The best part is, you can add as many Dojo's as you want! Raising their levels will be pretty tricky too. You can also add a kitchen to your Join Avenue. When it is at level 8, you will be able to raise your levels by 3 each day. Once it has reached Level 10, you will be able to train your Pokémon by up to 8 levels everyday! This can take a while, but the Join Avenue is addicting! Keep using these options daily and you will get to Level 100 in time. Confused still? Click here for a tutorial on how to use Join Avenue!
One more thing you could do is have a Pokémon visit the dreamworld: If it gets a heart bubble (More than 500 dream points acquired), it will level up when you wake it up! Besides, after about 10.000 dream points, you can find Rare Candies sometimes. It's useful for the latest levels that require lots of exp. to get! Beware though, that both the Dreamworld and Join Avenue level-ups won't evolve your Pokémon or let it learn any new moves! So you might want to use a rare candy for it to evolve or just before it learns a move, or take it to the move relearner with a heart scale.
My sister uses the heck out of Join Avenue. Since she has the Dojo completely leveled, she also uses that too. So you can gain quite a lot of levels each day :'D I still have to do this myself but yeah. Haha. She has like...8 level 100s now X__x
...Or you can just get un-legit Pokémon. But yes, this new feature is quite interesting. I have not seen this before, and I may look further into this. Of course, I do miss the auto Level 100 on Wi-Fi battles in D/P/P, did they restore that in B2/W2, or is it still the same as B/W?
Getting unlegit Pokémon is okay I guess, I've done it in the past. But to be honest, I'd rather just have legit Pokémon since it shows you actually put the effort in. I didn't create this thread for battling purposes anyways, I made it for people who want lvl 100's ingame, for battles such as Black Tower and White Tree Hollow.
Oh money really isn't a problem post-game, you can just fight the Black Tower/White Tree Hollow trainers over and over again, or the Elite 4, and get some traditional leveling in while you earn the bucks.
Yeah the same thing happened to me once, even though I changed the time months prior to putting in Black 2 again. What I found fixes it is to make sure you have your DS on as the clock changes to midnight and a new day. Simply turning it on the next day without the game being on as the day changes doesn't fix it.
