【The Witch of Rust】A.A. Analysis

Multi-Target Magical Skill

Severing Rust

Severing Rust is a vital, multiple-targeting magical skill that scales well with ATK. At level 3, it fires 4 attacks, each dealing 710% of your ATK, for a potential total of 2840% damage. While powerful, its effectiveness relies heavily on your ATK.

Damage and Healing Scale with MAG

Limiter Release

This multi-target skill hits four randomly selected enemies with 200%–420% MAG damage while healing the A.A. with 15%–20% of the damage dealt. It attacks numerous targets and requires a strong MAG. Level 4 allows it to deal 1680% MAG damage and heal for 336% MAG, making it an effective weapon for A.A.'s self-defense and offensive purposes.

【The Witch of Rust】A.A. Best Runes

Boost for A.A.'s Multi-Target Mayhem

ATK Runes are your best friend in Severing Rust, but don't forget about HP and CRIT Runes to stay alive. At higher levels, the multi-target skill prefers MAG Runes, while CRIT Runes can provide some burst. If you lack debuffs, consider PMDB and Debuff RES Runes if your opponents devastate you.

【The Witch of Rust】A.A. Best Team Comps

A.A. Attack Team

DPS	Support	DPS	Debuffer	Buffer
A.A.	Merlyn	Cordie	Mimi	Primavera

A.A. needed a team that could give her support so she could shine. Primavera's buffs can increase damage, while Merlyn cleanses and keeps them alive. A.A. becomes a DPS monster with Primavera and Merlyn, so add Cordie and Mimi for additional combat power and debuff.
