Skill capes would be for anyone who gets a skill to lv100. Example a Necromancer with lv100 could get a Green skeleton on a cape that drips green oozing poison pixels 
Capes of Achievement would be harder to get, example Murder 1000 players get a "Murderer Cape" With a Knife in a Heart or a Warhammer Smashing a Skull that glows a Black and Red Aura around the cape dripping blood in the words "Murderer Beware on the ground"
"YES I UNDERSTAND THERE IS ALREADY TITLES... But they seem like they are lacking in EPICNESS"
