The Howling Abyss is used for "ARAM" (All Random All Mid) matches, and is five vs. five.  The difference between the Abyss and the other maps is that there is only a single narrow lane of Turrets and an Inhibitor, and no neutral jungle area. Thus, rather than skirmishes and hidden movement, the Abyss focuses exclusively on large team-fights in the sole middle lane. Players cannot return to their allied base to replenish health and mana or purchase items unless they have been killed.  ARAM was launched as an official mode in September 2013. 
Hi Diana, its good that you took this step at asking PayPal this very asked question, good job Diana, thanks. I use PayPal and Moneybookers (Skrill) every single day, and I know about that transfer that is not allowed from PayPal to Skrill and from Skrill to PayPal, but I can tell you how people help each other.
If you want to purchase from Ebay or some other websites that allow PayPal than you need to have funds on PayPal, but if someone wants to withdraw their money they use Skrill a lot, because it is more cheaper.
So if I want money on my PayPal I just try to find someone who wants money on Skrill, and we do the transfer, I send him on Skrill and he sends me to PayPal, very easy and helpful, but you need to be extra careful because there are a lot of scam people that will use your need and never give you your money, please be careful when you do this.
I like PayPal and Skrill they are awesome, but the only think that I hate much about PayPal is that the fee is very large when you send money from one PayPal account to other PayPal account, the fee is extremely huge, if you send 2$ to other account, PayPal will take you $ as a fee which is very large. In Skrill that is very chceap, sending money from one Skrill to another Skrill is very very cheap, couple of cents.
That’s my experience with this two sites, if you are interested in some money transfer you can contact me, because I need money on Skrill, so if you are interested I will give you money on PayPal and you will give me money on Skrill. For every transfer I will give you a little bonus, because I really need that transfer, thanks, hope I helped a lot from you guys. Regards.
