Electro-Lip Gloss

A strong A-Rank option with Anomaly Proficiency, ATK and bonus DMG. Aria keeps enemies under Corruption almost constantly, so the effect is practically always on. On average it's less than 5% behind Flight of Fancy.

Burnice makes full use of its stats. She applies Burn so quickly that the condition of enemies being under an Anomaly is almost always met. It's even more consistent in Disorder teams.

Strong when enemies are already afflicted by an Anomaly before Miyabi attacks, so it suits teams that apply Anomalies constantly; weaker when that condition can't be maintained.

An alternative: Anomaly Proficiency as its secondary stat, plus ATK and bonus DMG while an enemy on the field has an Anomaly, which is almost always true in Anomaly teams.

A passable Battle Pass option: enemies are almost always under an Anomaly, so its buff is nearly always active. However, its DMG bonus tends to be diluted and its ATK and Anomaly Proficiency fall behind Weeping Gemini, so it's usually only worth it in high-Stun teams.

A Battle Pass W-Engine that can be very strong or fairly weak depending on the situation. Only use it when a teammate applies Anomaly before Grace or keeps an Anomaly up on enemies at all times.

The easiest Battle Pass option: decent stats and an effect that is almost always active on Promeia, with nothing to manage. Its bonuses are low, so it only beats Weeping Gemini in fights or teams with a very high Stun count.

Gives Anomaly Proficiency, combat ATK and bonus DMG. The effect is almost always active since Polarized Assault counts as an Anomaly. It performs on par with or slightly below Weeping Gemini, so it's only worth using if you already own it at S5.

An alternative: more ATK and more DMG against the target while an enemy on the field is under an Anomaly, a condition Jane meets easily.

Consistent in every situation: its ATK and DMG bonuses are almost always active. Other A-Rank W-Engines can match or beat it, but they need buff management or specific teams.
