I'm lvl 46 now, planning to leveling fast to CP 160 (used to just wandering around earning exp randomly). I want to use the 50% potion, but not sure which way would be most effective time wise. Should I do quests (which ones?), grind (public dungeons?overland spot?others?), or something else? I only want to get to cp 160 before going back to my wandering way, and prefer to do it solo if possible. Any advice is appreciated!
