So I'm training my pet to fight in the BD (hopefully in the plot too). I just hit the 20/20 boost yesterday and I'm hoping to get to the 35/35 boost before we have to fight anything in the plot.

I'm currently training at the island using codestones. My question is this- when is it optimal for me to start doing kitchen quests? Should I start doing them now as long as each quest costs under 12k, or should I wait until the island starts charging me 2 codestones per training session?

Also, should I bother with stat raising potions (yet)?
