Also, worth noting, from Player's Handbook page 67:
When a set bonus is achieved by equipping a weapon, shield, orb, or anything held in (not worn on) the hand, the hand-held item is “locked in” for that mode of combat. Therefore: • If you equip a hand-held item in a melee slot to fulfill a set bonus, you must keep that specific hand-held item equipped if you choose to engage in melee combat. • If you equip a hand-held item in a ranged slot to fulfill a set bonus, you must keep that specific hand-held item equipped if you choose to engage in physical ranged combat. You may temporarily swap one or both hand-held set-piece items (either melee for ranged or ranged for melee) and maintain the set’s bonus. However, the bonuses granted by the individual “lost” item(s) won’t apply. E.g., a ranger using SCEPTER, ORB, and BOOTS OF MIGHT to gain a level may swap out the scepter and orb to use a ranged weapon, but may not use any other melee weapons. During the swap-out, the ranger loses the +2 Strength bonus granted by the ORB OF MIGHT, but maintains the +1 level granted by the Might set. Set Bonuses and Duplicate Weapons To qualify for a set bonus, the set’s quota must be filled with unique items if the items are Ultra Rare or lower in rarity. E.g., a ranger may wield two +1 MITHRAL LONG SWORDS, but they only count as one when it comes to qualifying for the Mithral set bonus. However, if both of the set weapons are either Relics () or Legendaries, they count as two items toward the set’s quota.
