40 - Legend emote 1
50 - Legend emote 2 + ( i guess random icon cuz i received a pentakill icon )
60 - A better box for champ shards ? xD
Levling Method :
Coop game vs ( Middle bots ) not the easy ones.
End after 8 mins , 1 stays toplane , 2 pushes botlane as example trist + jinx.
With both Exp boosts day+wins u get 300-330 exp or smth around this for this quick time.
P.S Remember only works when u have both exp boosts on ~
