Variation

Variation is an operation mechanic featured in Zwillingstürme im Herbst.

Overview

Leithanien is known for its music, which have dynamic variations that affects how enemies attack and even granting additional abilities for some.

Variation is represented by special visual effects around the screen and a music sheet-like bar shown on the HUD. As the operation progresses, a musical note will gradually move along the bar; when this note stays on the sheet's yellow section, the variation turns passionate and yellow sound waves will be shown at the edges of the screen. Similarly, when the note stays on the sheet's purple section, the variation turns melancholic, and purple sound waves will be shown. However, no variation will be active when the note stays on neither of these two sections.

• In the passionate variation, enemies have their ASPD increased by 50 and movement speed doubled, but have their DEF halved.
• In the melancholic variation, enemies have their ATK increased by 20% but have their ASPD and MSPD reduced by 50 and 50%, respectively.

Tuning Nodes can be used to switch the active variation by activating it when either variation is in effect.

Enemies whose special abilities are enabled in a variation (see below) have a yellow cross or a purple circle mark above them, which glows brightly during the corresponding variation.

	His Sovereign's Edict forcibly activates a variation, during which all enemies have their ASPD further increased by 10 in the passionate variation or have their ATK further increased by 10% in the melancholic variation. Enemies that are Stunned at any point during a Sovereign's Edict variation will be punished by taking heavy Arts damage after it ends.

Trivia

During the Sovereign's Edict variations, the variation meter has only one section and the BGM is altered depending on the variation in question; for more information, see Zwillingstürme im Herbst/BGM.
