1) Create a Alternative character on the account you want the double experience to be activated on.2) Get the reward box at lvl 1 quest which pops up right after you start playing in new character. (this box has rewards and has twenty-four 30min double EXP scrolls you will need to use which are limited to character below level 36 to use)3) Simply leveling the alternative character by yourself or getting a friend to help you level the character (Recommend Witch Cliff) TILL LEVEL 36 if you level pass Level 36 on the Alternative character you will not be allowed to use the double EXP scrolls and will have ruined the process.[ Double EXP scrolls on Lucent Heart are shared across all characters on the account which allows you to active them on any character and be applied to another now congratulations you now have 12 hours of free double EXP every 3 days for grinding purposes]
