Arena Energy is like a currency
do not waste it on random people!!!
mantain the exp within the clan.


the most effective way to level in a fast way is to exchange
its very easy for every energy u have u can multiply it by 2 how??

well go to battle arena, and type exchange with anybody,
once u have somebody to exchange u sent him 2 fights, in return they sent u 2

preferible is good if you win the fight, but if you are progressing
then it doenst matter, as long as you get ninja exp,

in my case im a camper, so i need summon exp, so every timei challange i try to get an exchange,

that way i dont give away my precious energy to people that wont return the favor,
a good way to do this is either go to BW chat

or in battle arena chat

will edit for more.

Good but im too lazy to exchange ppl, so i just send rendoms D:
