Is it okay to use Rare Candys to get from level 20 to level 42? I am currently doing the Professor Oak challenge in Sapphire and I use the Pick Up Abilities (obviously) but I have enough Rare Candys to just take my Aron from level 20 to level 42 and still have enough to get my Tentacool who is level 13 to evolve to Tentacruel at level 30. Is it okay or is it taking the fun out of it?
