Either don't exist or don't work.

I assume you were refering to stuff like

Pandamonium
Lacerations
Devine Light

ect.. ect..

You can't make them, have tried...many ways

Either they are broke or you are refering to some other special recipies that players
will never discover because it is expensive enuff to make combos that we know,
let alone waste expensive shards ...by the hundreds in hope of finding some
weird combination.

Drop the mystery...publish a list or fix the current crafting mechnics so the new combos work.

enuff said
