>>43985582In case you have these, my first clear was with 12 pairs and the struggle obviously came from the last hp bar and entei being more active, with these three I did replay and managed to solo it thanks to hydro grid on misty, acerola only needs aggravation if you don't have many orbs, misty however would like a full grid. The Eevee is also Vigilance as the only skill one would want to prioritize.
Barry would have been good for you, yes.
Look up some youtube vids for f2p cleans with more than one team for stage 3 entei.
