Best in Slot Magic Item(s)
Grading system:
Orange indicates BiS with almost no exceptions
***Indicates generally accepted as unquestioned BiS
**Indicates used in most builds but there are exception cases
Back - Pharacus's Greater Cloak of Destiny***
Bead - Bead of the Lucky Traveller***/Master Ale Drinker's Bead**/Bead of Guided Strike** (fighter/rogue) or Bead of Focus (casters) ** or Bead of Cleric's Piety (anyone who can't use focus or guided strike)**
Charm (give 3) - CoAS***/Charm of Glory***/No clear #3 (A good case can be made for any of the following: Broaching, Heroism (for those who don't get 5th level another way), Quick Strike, Spell Storing, Draco-Lich, Garnet, or Lucky Charm.)
Ear - Arcane Earcuff*** (except for Paladin due to charm necklace)/Orbits (for spellcasters)** or Ravager** (for melee)
Eyes - Instant Analysis (for melee)***, Divine Sight (for clerics/druids)***, Agility (rogues)*** - for everyone else no clear BiS (Psyferres and Sniper are likely the two most common)
Feet - BoFW***
Figurine - Phoenix** (Paladin/Cleric) and Owl** (Druid/Ranger) - otherwise no clear BiS (Cat, Panther, Raven, Tortoise, Dragon, and Pixie are the closest)
Finger - Muk's Greater Ring of Havok***/Relsa's*** (for spellcasters) - otherwise no clear BiS for the 2nd ring (SRoEC, Heroism, Quick Blessing, Expertise, Wonder, Eel or Yeti all have a case for a 2nd or 3rd ring slot)
Hands - No BiS. Blessed Tempest (most likely BiS for bard/druid/wizard), Greater Archery, Death Knight, Flying Fists, and Weapon Finesse are all candidates depending on the builds)
Head - No BiS - Cranston's is probably the most common (Cook's, Might, and Perns are likely the best - though Perns mainly to complete Redoubt set since AC isn't terribly important above HC)
Ioun Stone (give 3) - Mystic Orb*** (if you have the skull)/Jasper Ellipsoid and Fire Prism (melee)** or Banshee Prism** (ranged/spell)/No clear 3rd BiS (Garnett Cube, Elfstone Shard, Flourite Sphere (for healers), Charming Cabochan are likely the top contenders for that slot)
Legs - Kilt of Dungeonbane***
Mainhand (weapon) - +5 Deathcleaver (Barbarian)***, Ava's (Paladin)***, +5 Viper Strike Fang*** (Monk), +2 Assassin's Crossbow (Rogues)***, Drake's (Wizards)***, Dru's (Cleric/Druid)***, Widseth (Bard)***, after that no clear BiS (Welfor's/Thor's for mainhand with shield is very common (likely **) and Io's for Ranged Rangers (**).)
Neck - Legendary Necklaces for Barbarian/Cleric/Fighters/Monk/Rogue/Wizards***, Ralson (Ranger)**, for Bard/Druid/Paladin Charm Necklace (depending on how close to 10 charms you have), otherwise no BiS for those classes
Offhand - +5 Viper*** (where applicable), Giln's*** (only for fighters), otherwise no BiS (best candidates Orb of Might where Viper can't be used and non-fighter, Shield of the Scholar (for casters), or +2 Mug of Battle)(also edge case - for ranged rangers - +2 archer's buckler for the ranged off-hand)
Runestone - No BiS (+to melee or ranged as applicable)
Shins - No BiS
Shirt - Focus** (for casters), Viper*** (for monks using 2 +5 strike fangs) otherwise no BiS (Oaf, Nimble, Blessed Strength are most common)
Torso (armor or robe) [divide into classes if possible] - Aron's*** (for all classes except Fighters and Paladin) (since AC isn't terribly important unless you are guarding or taunting), Byr's*** (Dw Fighter and Paladin)
Waist - Surtur's*** (melee classes), Orion's** (everyone else)
Wrist - Luna's*** (Bard, Cleric, Fighters, Paladin, Rogue, and Wizards) - Close choice between Luna's and Guided Strike for Barbarian, Druids using Iktomi's, and Rangers
I find it interesting that there are some uncontested BiS:
BoFW (feet)
Kilt of Dungeonbane (legs)
CoAS (charm)
Charm of Glory (charm) - ring slots are hyper-competitive so this becomes a must have
Surtur's (waist for melee characters)
Pharacus (back)
Muk's (ring)
Aron's (torso) - (for all non str-based classes or Paladins)
Instant Analysis (eyes for melee)
Divine Sight (eyes for clerics/druids)
Agility (eyes for rogues)
Luna's (wrist) for anyone who isn't crit-focuses and doesn't already get there otherwise (rogue/fighter)
Biggest surprises:
#1 - A rare made the list (even as an alternate) (Jasper's)
#2 - A Two UR's made it in slots where legendaries were available:
+2 Assassin's Crossbow (unquestioned BiS for rogues as the top damage option while also improving saves as a side effect)
Bracers of Guided Strike - amazing that these could even be considered against Luna's but for Barbarian and Iktomi using Druid (maybe Ranger too) - they seem to fit as BiS
#3 - An Eldritch item didn't make it as BiS (SRoEC) - often it doesn't make even as a 3rd ring
#4 - Iktomi's isn't BiS legendary for Druid (you can build a higher damage druid using the Charm necklace for both casting and polymorph)
