well i went to the place were the sword goes were the light crystal was a long time and there was a grip and light crystal but now the grips gone so how do you get the right sword combo to put the sword in the stone because the dev said that the parts matter and the secret grip goes to it so was it moved and removed form the game   

The secret grip has yet to be readded, The formula for the sword pedestal doesn't require it. There's a specific handle from the ones you can buy, a specific grip from the ones you can buy, and a specific sword which may or may not be the one you think it would be, that work as the combination for the formula.

If you want to figure it out yourself. This is all the info.

If you want spoilers, snoop around posts... there's spoilers here and there.
