Hello!
Thank you, COEUS, you are right again
This item does increase the XP points properly.
To see the difference clearly, try two battles: one with the activated item and the other without an item. Be sure to hit Warlords of the same level by Guardians of the same level. Then you will see how the points are doubled.
Have a great one!
