I've played these event 3 times already, you need 2k2-2k7 minor potions to reach 250, and 2k7-3k2 for 300. that's the rule for years and hasn't change at all. The only change is the reward packs. dont blame the system when you dont know how to calculate the way to win it. Your 999 potion saving is simply not enough to reach the goal.
