Re: Minor inconvenience (gems & coins wiped out)
@HenryThePear Just as @MAGICDAVESHROOM says, the shadow pea seed packet will be available to be exchanged with gems but this is an expensive way to get your plant levelling-up, I would suggest holding back the gem purchase until the last day to top up to the level you wanted, during the time it is on offer, there should be quests you can complete to earn seed packets for 'free'.
Most of us old players were able to get it to max for 'free' from the old Battlez streak system, the new Arena rewards in my opinion is not as friendly for new players as they made it out to be, maybe one day they have a change of heart but I would not hold my breath.....
