You can't do skill 4 and skill 3 is impossible, too.

Frodo its not imposibble, its just hard. Just because u aint up for it doesnt mean anybody else is. And I bet 2 years ago everyone said it would be imposible to steal hp or bury an enemy.
And I didnt add this post for ppl to say that its imposible when HOLLIDAY already said it can be done, but he doesnt have the time now

I tell you ultimate is impossible so IT IS impossible. Soldier is right, you can walk through everything and you don't lose your gun when you are inside a wall, you loose your gun forever. AJ, you can do this through keyvalues so on key go in, on key go out.

something like

first hit check if value blabla is 1
if its 1 this means you are in noclip
if its 0 this means it will execute code which will make you go in noclip

The ability is, right, depends on how you spell it... you have to tell us how should it exactly look.

Btw HOLLIDAY tell me how are you going to do this Coz i got idea but its a bit funny lol... BUT IT IS POSSIBLE!
