Halloween Lethe Best IVs

Recommended IVs

Stat	Superboon/Superbane	IV Recommendation
HP (18)		★★★☆☆
Atk (9)		★★★★☆
Spd (8)		★★★★★
Def (13)		★★★☆☆
Res (5)		★★☆☆☆

◯ = Stat gains +4 with a superboon, ✕= Stat goes down by -4 with a superbane, - = No assets or flaws

See the IV Checker for All Units

Trait Fruits—How to Change IVs

When using an Ascendant Floret, we recommend getting the next superboon if it fits the hero. If not, consider what stat your hero needs most.

+Spd / -Res

The best IVs for Halloween Lethe are +Spd and -Res. Halloween Lethe's Spd is among the highest in the game at base 47, and a superboon increases that to base 51. This boon allows Halloween Lethe to keep up with the fastest metagame units if properly invested.

Halloween Lethe's Res is lackluster at only base 24 and is a safe bane to take as investment won't impact any of her matchups.

+Spd for a +10 merge

We recommend a +Spd IV when merging Halloween Lethe up to +10 to ensure she keeps up with the fastest metagame units.

Halloween Lethe Roles, Strengths, and Weaknesses

Halloween Lethe Roles

Lethe - Cat Attack Roles

Physical Wall	Magic Wall	Effective Weapon	Movement Assist
Exclusive Skill	All-Range Counter	Recovery	Refresher
Legendary	Mythic	Duo / Harmonized	Resplendent

Halloween Lethe is a close physical attacker (range = 1). Therefore, when not accounting for the Weapon Triangle, the amount of damage she deals will be equivalent to her Atk minus the foe's Def stat.

Halloween Lethe Strengths

Hungry Cat Fang has built-in Time's Pulse 4 and Null Follow-Up

Halloween Lethe's Hungry Cat Fang has built-in Time's Pulse 4, speeding up her Special cooldown and improving her combat potential.

In combat, Hungry Cat Fang grants Halloween Lethe up to Atk/Spd/Def/Res+14 based on number of foes within 3 rows and 3 columns, a Null Follow-Up effect, the offensive half of Tempo, and 100% damage reduction piercing whenever her Special triggers.

Hungry Cat Fang also has standard Cavalry Beast transformation effects, including Atk+2, Atk/Def-X on Lethe's foe based on distance travelled, and 30% damage reduction on her foe's first attack.

Hungry Cat Fang is a weapon that encourages quick Special triggers to maximize Lethe's damage output.

Halloween Lethe Weaknesses

Weak to Beast Effective Weapons

Halloween Lethe takes 1.5x damage from beast-effective weapons like Brave Eliwood's Nini's Ice Lance or Picnic Flora's Sæhrímnir, and one blow from this type of weapon will deal significant damage. Make sure you know what weapons you are up against before hopping too far into the line of battle!
