Greater Shaman's Fury set bonus [+40% damage to Elemental spells], Charisma +6, Greater Evocation Focus, Efficient Metamagic - Maximize II

what are the exact name of the ingredients needed to craft this piece of shamans set?

ddowiki says its shaman's beads but there is only two kinds of scrolls/seals/shards i ve seen: shaman's brooch and shaman's band.

So which one of these scroll/seal/shard pieces belong to that item?
