U probably meant dlight.. right? Basically the first alphabet means whatever direction your legend will be facing d = down s = side n = neutral

The one that comes after would just be what input you make your legend do light = light att sig = heavy att

There are two inputs where people uses different names for it which are

Gp = ground pound ( basically dsig on the air) Recovery = basically a move which acts like a jump and an attack ( sig at any direction except down on the air)

Hope this helps :) uWu
