Previously denied before due invis effect not being supported... 1.4.2 now does!
An invisiblity suit that when worn (all parts are required) , gives off invisiblity potion effect. Similar to nightvision goggles, but with invisibility.
Invisibility suit should be in a tier between nano and quantum. Invisibility suit does NOT give ANY armor. Press M to cloak, again to uncloak.
Coding : To achieve full invisibility armor should have no render.

Well, i'm not completely invisible since i have GregTech cape and i have an item in hand.
Without cape and item in hand you should be perfectly invisible. Mobs don't hit you unless you touch them, and your name (Multiplayer) disappears.
GregoriusT : Are capes the same to everyone? Thanks anyway! (Even though i'm not able to donate [money] i can "donate" ideas and tests =D )
