There are several games that are based on the theme of sharing or sending gifts to the team or else to the neighbors by which the count would be increased. The satisfied neighbors are likely to send some other items that may add up to your treasure. Though not actually treasure, you could get more lives when you do couple of activities with multiple accounts. May be you need to improve the team strength or count for which you need to add more accounts into the same level of the game. There are games that are played as teams with as many members as you have or as many as the game demands you to make a team.
Also when you work as a team you could get more control on the game. Hence, until you gather some friends whom you know you could buy the league of legends accounts and keep them ready by changing the email Ids if required and start playing with each of these accounts on an alternative basis so that you have enough fun in playing the game. One ranked account would hardly be able to do anything in the games that are played as teams. So, all that you could do is to buy the accounts and start playing the game with these new accounts but those that are already made ready to be played from a certain level in the game.
Along with being able to play as a team with these multiple accounts being operated on a daily basis you are able to get some resources on a daily basis which would add up to your total treasure as a whole team. Thus, it is good that you buy the accounts and have enough excitement while playing the game.
