Sully

Preferred IV: +ATK or +SPD/ -HP

Sully’s neutral Attack is simply awful, so increasing it is a top priority. If a +ATK IV simply isn’t available, though, +SPD can be used instead to deny follow-ups.

Weapon: Bull Spear (+Atk) / Bull Spear (+Spd) / Sapphire Lance

• Considering its higher mt and ability to be refined for extra stats, there’s absolutely no reason not to use the Bull Spear over Sully’s default Sapphire Lance.

• Unfortunately, the Bull Spear’s effect refine does not synergize well with Sully’s statline since she is not particularly defensively bulky.

• For this reason, it’s a better idea just to take some free Attack (or Speed) rather than trying to work around the Bull Spear’s restrictions. An Attack refine is preferable, however, given Sully’s relatively low Attack at neutral.

• In a pinch, the Sapphire Lance can also be used as well.

Assist: Draw Back / Flexible 

• Draw Back is Sully’s native Assist and can be useful for strike and retreat strategies, but really, any Assist can be used here depending on the team’s needs.

Special: Luna / Moonbow

• Given Sully does not have any particularly impressive defensive stats to scale her Special proc off of, the straight Defense reduction that Luna provides will help her break through bulkier foes. Moreover, Sully’s unimpressive Attack makes Specials that scale off Attack – such as Glimmer and Dragon Fang –  poor choices for her.

• Moonbow can be used instead as a lower cooldown alternative at the cost of dealing less damage.

Passive A: Fury

• Since Sully does not excel in any particular area, she appreciates the straight stat boost Fury will grant her more than most units do.

• While the recoil from this Skill is less than ideal, its general utility is higher than exclusively Player Phase or Enemy Phase focused Skills.

Passive B: Swordbreaker

• Since Sully’s primary role should be as a red counter, her native Swordbreaker helps her perform more efficiently against meta sword units like Fallen Mareeta.

Passive C: Hone Cavalry / Spur Def / Flexible 

• Regardless of her C-Skill, Sully will perform largely the same. Therefore any Skill can be used here depending on the type of support that is needed in the team.

Sacred Seal: Attack +3 / Speed +3 / Brazen Atk/Spd

• Given Sully’s low Attack, a further boost to it can’t possibly hurt. Likewise, her middling Speed also could make good use of a few extra stat points. Alternatively, and since Sully will likely be taking some damage in her first engagement, Brazen Atk/Spd gives her a substantial increase to both these stats once her HP is below 80%.

Preferred IV: +ATK or +SPD / -HP

Once again, a boost to Sully’s Attack is preferable here since it is so low at neutral. If follow-ups are of greater concern, however, +SPD can be used instead.

Weapon: Firesweep Lance  

• Because Sully’s defensive stats aren’t particularly good, she will perform better when her foes can’t hit her back. The Firesweep Lance safely allows her to do this – assuming they are not carrying Null Follow-Up.

• Sully will be unable to attack on Enemy Phase with this weapon, though, meaning that she will have to KO her foe outright, rely on an assist from a team member, or retreat once she attacks.

Assist: Draw Back / Flexible

• Once again, Draw Back is Sully’s native Assist that can be of use in certain scenarios. However, any Assist can be used here.

Special: Luna 

• Since Sully will not be activating Moonbow on her first engagement (as she will not be counterattacked), she might as well take advantage of the extra damage Luna will deal on the next Player Phase.

• To reiterate, Luna is suggested over stat-scaling Specials (like Dragon Fang, Bonfire, and Iceberg) due to Sully’s low Attack and unimpressive defensive stats.

Passive A: Life and Death / Brazen Atk/Spd

• Life and Death -- despite decreasing Sully’s Defense and Resistance by five -- actually helps her survivability by allowing her to avoid enemy follow ups during both Player and Enemy Phase.

• While other options like Swift Sparrow 3 and Atk/Spd Solo offer higher boosts to her offensive stats, their rarity and the fact that they only apply during Player Phase make them less versatile in Sully’s case. 

• Brazen Atk/Spd is another accessible alternative that gives Sully a significant offensive boost once her HP falls below 80%. Since it would result in a very lackluster first engagement though, it is not the primary recommendation.

Passive B: Drag Back / Hit and Run

• Drag Back and Hit and Run are interchangeable options for Firesweep users, allowing them to retreat after attacking and be swapped or repositioned to safety.

• Drag Back is the primary recommended Skill, however, since it can help Sully move an enemy into the range of a powerful magic, staff, dagger, or bow-wielding ally.

Passive C: Hone Cavalry / Spur Def / Flexible 

• Like in her first build, choice of C-Skill really doesn’t matter for Sully. She can use any Skill that her team requires of her.

Sacred Seal: Speed +3 / Brazen Atk/Spd / Darting Blow

• While Sully would likely appreciate a further boost to her Attack, raising her Speed allows her to deny more follow-ups on Enemy Phase and therefore survive longer. 

• Sully can also stack Brazens to gain a whopping +14 Attack and Speed when she is below 80% HP, but that means for her first engagement she will be rather slow without support.

• Darting Blow offers an even greater +6 boost to Sully’s Speed in exchange for only being active on Player Phase, but if Sully is under the effects of Cavalry Buffs she will likely survive Enemy Phase regardless. ​​​​​​​
