needing help on dual tier 3 shard

[Mentos3111]

basically i have everything crafted for two seperate supremes and an extra empty supreme so 3 un-used total.
been looking on net i am unable to find actual info regarding dual tier 3.
do i combine the two i want together with power shard and empty supreme or do i just combine the two with a power shard alone? thanks in advance for the help.

You only need 2 supreme power shards.

You imbue each supreme power shard according to its own recipe.

Once you have the 2 imbued supreme power shards, you combine them both in the altar, plus a high energy cell.

This will create a new single imbued supreme power shard that contains the powers of the 2 previous ones (might have a slightly different name, I dont remember). You combine it in the altar with your greensteel item plus a high energy cell, and you are done.
