Fenny Analysis

Unleash AoE Damage and Crippling Debuffs

Jamming Scattershot

Fenny's skill is a great AoE skill that significantly damages multiple opponents and provides valuable debuffs. The skill has a 40% chance to apply a two-turn [Buff Immunity] and a 40% chance to [Decreased Chance to Inflict a Debuff] by 50%. Both the duration and the likelihood of applying debuffs increase with skill level. Fenny's Jamming Scattershot is a powerful asset for controlling the battlefield.

Devastating Single-Target Skill Debuff

Magic Permeator

Magic Permeator is a powerful single-target skill that deals significant damage and has a chance to inflict a debuff that causes continuous damage over time. The skill's damage increases with each use, and it can be further enhanced by upgrading it.

Fenny Best Runes

PMDB Runes For Battle Control

We advise players to use ATK, PM. DEF Break, Debuff ACC, and SPD runes for Fenny's AoE skill, Jamming Scattershot, to optimize her offensive ability and battlefield control while boosting her survivability. The same offensive and defensive rune combination—Debuff ACC, SPD, Crit RES, and Debuff RES—is suggested for her single-target talent, Magic Permeator. Her balanced rune arrangement ensures Fenny's efficiency in diverse battle conditions.

Fenny Best Team Comps

Azure Soul Affinity PVP Team

DPS	Debuffer	Debuffer	Buffer	Buffer
Florence	Fenny	Soltina	Primavera	Fenrir

The two active abilities that Fenny possesses, Magic Permeator for single-target damage and Jamming Scattershot for AoE damage, enhance the variety of abilities that her teammates have. Florence's critical hit concentration and Soltina's defensive skill set balance out the attacking power of the squad, while Fenrir's speed boost works in harmony with it. Primavera is a versatile unit used in various battle settings because of its crowd control and team boosts. Because most of the characters in the team belongs to the Azure Soul Affinity category, they are also given a boost with their HP and ATK.
