Here is a guide made by the best ZvZer on asia, his name is Zyrion so i take no credit for it
Tired of explaining this, hopefully now you wont be lost in this incredible labyrinth of "the corner of your screen"
An ancient trick used by amazon masters since 1.09
C/T is basically has no meaning other than Character screen / Tree screen, C/Ting is used mainly for extending your mouse beyond the normal capabilities of your screen, giving you an advantage in many types of dueling, mainly AmaPK, as this can extend the range at which your arrows are being curved at, for characters with teleport, and other many creative uses.
For this section I will be explaining this as easily as I can for amapk (Don't worry friend, as the great master Zyrion is aware that pictograms are worth 1000 words)
Red dot: Mouse placement for C/T (Look closer... closer.. BOO)
Red area: Area of curvature
Green area: Safe area of curvature when using either C or T to one side
Black box: Possible arrow detour curve from both C and T, and full mouse placement mid-screen
Note: Boxes represent automap area, not real-time radiusNote: First box is vastly oversizedHow to use C/T to your advantage; pushing the mid-range (not rushing down your opponent like a moron, won't work) when you push the mid-range all this means is you are playing offensively to maintain your opponent within that red area so that your arrows will curve and will always hit the target, don't worry if you can't do this for 5 more years, after all, あなたは10年早過ぎにです, You are 10 years too early
