Understand On the Fall of an Aeon
Useful when…
- For wearers who attack during battle and can build the battle-long ATK increase.
- For wearers who can personally break an enemy’s Weakness to activate the temporary DMG bonus.
How do its effects work?
When the wearer attacks, their ATK increases for the battle, stacking up to four times. This is a battle-long stack limit, not an increase per enemy hit. Separately, after the wearer breaks an enemy’s Weakness, DMG dealt increases for two turns.
When is it a practical fit?
The ATK effect builds during battle through the wearer’s attacks, independently of the Weakness Break effect. The temporary DMG increase requires the wearer to break an enemy’s Weakness; the supplied effect does not specify that an ally’s break triggers it for the wearer.
Promotion and superimposition
Promotion uses materials such as Credit and Extinguished Core for the first listed step, and Credit, Lifeless Blade, and Glimmering Core for the listed stage 3-to-4 step. Superimposition increases the listed ATK and post-break DMG values; its example steps use Superimposer (Custom-made).
How do other Destruction effects differ?
A Secret Vow increases DMG dealt and adds damage against enemies whose current HP percentage is at least the wearer’s. A Trail of Bygone Blood increases CRIT Rate and Skill and Ultimate DMG. A Thankless Coronation increases CRIT DMG and has Ultimate-triggered ATK effects, including a Max Energy threshold for its additional effect. These effects have conditions distinct from this Light Cone’s battle-long ATK stacks and wearer-triggered Weakness Break bonus.
Limitations and tradeoffs
- The ATK increase stacks up to four times during battle.
- The two-turn DMG increase requires the wearer to break an enemy’s Weakness.
- Superimposition uses Superimposer (Custom-made) in the listed upgrade steps.
Common mistakes to avoid
- Claiming each enemy hit adds an ATK stack.
- Expecting more than four ATK stacks.
- Assuming an ally’s Weakness Break triggers the wearer’s DMG bonus.
