| Slot 3 (Rainbow or lower) | Richard | Rippling Slice | His best DPS/supportive skill |
| Slot 3 (Rainbow or lower) | Hayes | Declare over Rebut but both not bad | While both of these skills do the same amount of damage, the cheaper skill Declare is better used as a finisher move while Rebut is more of a breaker move |
| Slot 3 (Rainbow or lower) | Hasumi | Celestial Song | Her best light DPS skill |
| Slot 3 (Rainbow or lower) | Kersjes | Sturdy Peerless Shot | His best bow DPS skill |
| Slot 3 (Rainbow or lower) | Nicola | No good or bad options | She’s not a DPS, so there isn’t any good or bad options here |
| Slot 3 (Rainbow or lower) | Cardona | Triple Valiant Charge | Her best spear DPS is also AOE |
| Slot 3 (Rainbow or lower) | Stead | Duskfall (Single) IV | His best dark DPS nuke |
| Slot 3 (Rainbow or lower) | Lars | Brutal Blazing Blade AND Wild Blazing Slash | You’ll want to build two weapons for him, as both of these soul skills are so good based on the situation |
| Slot 3 (Rainbow or lower) | Lumis | Esoteric Salve | She’s not a DPS, so boost her healing potency |
| Slot 3 (Rainbow or lower) | Heathcote | No good or bad options | His DPS is on the lower side and his role is shield cracking |
| Slot 3 (Rainbow or lower) | Therese | Lightning Blast (Single) II or Tonitrus Canere (All) | Her highest DPS skill is her 2-hit single target; her highest AOE DPS is 3-hit |
| Slot 3 (Rainbow or lower) | Z’aanta | With the Tide | Best DPS skill is 5-hit |
| Slot 3 (Rainbow or lower) | Primrose | Dirge of Dusk II | Her best dark DPS skill is 3-hit random target |
| Slot 3 (Rainbow or lower) | Molrusso | Ethereal Healing (All) III | She’s a healer, so boost her Regen potency |
| Slot 3 (Rainbow or lower) | Lynette | No good or bad options | She’s not a DPS; and you’ll generally have her equipped with Brave Fan which further reduces her DPS |
| Slot 3 (Rainbow or lower) | Theo | Duel Harvest | Duel is good if he is your Axe DPS |
| Slot 3 (Rainbow or lower) | Viola | Triple Edge | Not really any good options here, but Triple Edge is her best DPS skill |
| Slot 3 (Rainbow or lower) | Millard | No good or bad options | Don’t build a weapon for him TBH |
| Slot 3 (Rainbow or lower) | Gilderoy | Healing Thrust | His highest DPS skill also heals him |
| Slot 3 (Rainbow or lower) | Scarecrow | Double Sturdy Shot or Shower of Arrows | His highest DPS skill is 2-hit; but his 4-hit AOE is also really good |
| Slot 3 (Rainbow or lower) | Fiore | Crumbling Cut; rarely Double Arching Blow | Her best DPS skill is single target; though her AOE skill is useful in niche scenarios; if you easily reach damage cap then go AOE |
| Slot 3 (Rainbow or lower) | Sofia | Glacies Claudere (Single) III or Icewind (All) III | Her single target DPS is the best at nuking; but her AOE skill is best at speed farming mobs for materials |
| Slot 3 (Rainbow or lower) | Alfyn | No good or bad options | He doesn’t do enough damage and his role is supporting/breaking. |
| Slot 3 (Rainbow or lower) | Tressa | Trade Typhoon or Swift Trifold Thrust | Depends if you need her as your wind DPS. If not, go Trifold Thrust. |
| Slot 3 (Rainbow or lower) | H’aanit | Cripling Shot or Arrowstorm | Go with her strongest single target nuking option, or her best breaking option |
| Slot 3 (Rainbow or lower) | Cyrus 1 | Ignis Ardere (All) III | Always go for his triple hit skill |
| Slot 3 (Rainbow or lower) | Cyrus 2 | Glacies Claudere (All) III | Always go for his triple hit skill |
| Slot 3 (Rainbow or lower) | Cyrus 3 | Tonitrus Canere (All) III | Always go for his triple hit skill |
| Slot 3 (Rainbow or lower) | Therion | Paralyzing Tooth or Triple Bite or Hellfire | Paralyzing Tooth is currently his strongest nuke – choose it if you’re nowhere close to reaching damage cap. Triple Bite is the best long term option, and Hellfire is the best fire DPS option when built with Fortune eatk dagger. |
| Slot 3 (Rainbow or lower) | Tikilen | Slicing Winds | Her strongest 4-hit wind attack on a single target |
| Slot 3 (Rainbow or lower) | Glossom | Stout Twofold Blow | This is his strongest fan damage option; 2 hit, unlikely to hit damage cap. |
| Slot 3 (Rainbow or lower) | 2B | Trifold Cleave or Trifold Slash | 2B is likely to ram damage cap, so go with her triple attack skills |
| Slot 3 (Rainbow or lower) | A2 1 | Triple Edge | A2 is likely to ram damage cap, so go with her triple attack skills |
| Slot 3 (Rainbow or lower) | 9S | A150: Volt | His strongest lightning attack; not on the same level as Millard but there’s not really good options here |
