Exp accumulation potion

Just a bit curious, does it stack with any other buff? such as family/random 2x buffs

There are 3 kinds of EXP boosts not counting items such as Pendant of the Spirits or Mercedes Link Skill; the server event, the CS coupon and those that work as buffs and show among your characters buffs on screen. As a general rule, they do not stack with others of the same type. If you have a family buff on, using Maple Admins 1.5 x EXP buff would cancel the family buff out.
