that price 30 could be modifed baesd on popularity , demand etc ;
If the prices are not realistic , a least i provided a list.
PS:
also ,the reward system that also existed , rewaring ,keys popostones ,revive stones , xp boosters , skill reset books (1 point),fuel for mounts,etc.
PS:
also , the token system , had goku's dogi(guess that wont change) //many people would stay afk for the tokens , a rework sould be nice
1 token per kill as long as the mob is >= in level than you , also more tokens for completing TMQ , UDs )
you coud add more items to the token system.
PS : you coud add a dragon ball detector (anyone who has the item equiped coud hunt for dragonball anytime) //consumable last 2H ,4H, 8H variations .
