Sry, but I don't understand your question. What exactly do you want to know? How many artifacts you need per set? That is different for the several sets and it's written in the set description. For a speed set, for example, you need 2 pieces, so you can equip up to 3 complete speed sets. A regeneration set, for example, needs 4 pieces, you can equip only one complete set and would have room for 2 more pieces.
