I will post a simple method EndScene for League of Legends..

You can make a hacker, If you hack League of Legends and find adress, you can make a menu

[ekosins]

u wot, i couldnt really understand what you said lol

[[MPGH]Mayion]

It just writes text on the client.

He just made a hook for league of legends which enables you to draw stuff over the game UI.
And the adress part is about something like cooldown, when you disable a cooldown adress, maybe you can have a no-cooldown hack.
But i believe cooldown is serversided so dont mind trying or asking.

Great Leech! I mean work
Actually, you could use VTable to hook DirectX Functions.

This is pretty useless, but still great leech! I mean work.
