Why me ?!?!

When i was in arena playing with my uncle,on my screen i saw him far away from me but could still asal me, its like range asal. He was  full speed but he  seems far way from my screen .

One of the terms that discribes this issue, is position lagg. As you can see in the YouTube video above, it takes a certain amount of time before the game registers another player's movement, like in the game window on the right side in the YouTube video. In this way, you may asal a target player from normal skill range while the target player thinks that you are actually casting the skill from a far distance. This is only my theory, though. Try to do ranged asal with Sonic Hand
