Best Place to Grind for E4 in Omega Ruby?

[CodeCass]

So I'm (hopefully) about to finish my Nuzlocke of Omega Ruby.

 

I suffered a loss though in Victory Road where my Zangoose was killed. So I'm brining in my Nuzleaf to help fill the gap. My issue now though is that all of my team are 52+, and my Nuzleaf is 21. I'm trying to level him up appropriately so I can evolve him to max effect and get ready to finish this game ASAP!

 

So my question is, where is the best place to grind up a low-level Pokémon to get it ready for the Elite 4 in Omega Ruby?

 

Thanks so much for any and all help folks! I greatly appreciate it!

Make sure to beat every trainers , especially the ones in the water , there are a lot of them. Otherwise my advice is : go train vs wild mons on your level.

id stay in victory road but only have the nuzleaf in the party so the other mons dont take experience away  and switch train it until he can fight the mons there himself.

 

you can fish for barboach with a super rod level 30-40 on the second floor (four times effective hits)

and wailmer and luvdisc on the first level level 30-40 on the other floors (wailmer should give good experience)

how much do you want your other members to level up or they gonna stay at 52

 

level 28 nuzleaf with leafblade guaranteed knockout on a level 40 barboach 

barboach at level 40 give about 530 exp

wailmer at 40 give 738 ish exp

 

other benifits you can chain fish the barboach or the wailmer 

 

acutally you should go to meteor falls and super rod wishcash and chain hunt it for experience and shiny

 

here is a video on how to chain fish if you are not familiar
