Light Cone Ability

The Light Cone Ability of Honkai Star Rail The Day The Cosmos Fell is called Stratagem. This ability has two key effects. It increases the wearer’s ATK, starting at 16% at Superimposition Level 1 and scaling up to 24% at Level 5. This ATK bonus enhances the damage output of Erudition characters, making their attacks more potent.

Stratagem also increases the wearer’s CRIT DMG under specific conditions. When the wearer attacks and at least two enemies have the corresponding Weakness, their CRIT DMG increases by 20% for 2 turns. At Superimposition Level 5, this bonus rises to 40%. The effect encourages targeting multiple weak enemies, making it particularly effective in battles with numerous foes.

The ability only applies to characters of the Path of Erudition, ensuring that its buffs align with their strengths. Since Erudition characters specialize in Area-of-Effect (AoE) attacks, they can more reliably activate the CRIT DMG boost compared to single-target units.

In summary, Honkai Star Rail The Day The Cosmos Fell provides a consistent ATK boost and a conditional but powerful CRIT DMG increase in multi-enemy encounters. This makes it an excellent choice for Erudition characters who excel at hitting multiple enemies at once, maximizing its benefits in both regular battles and challenging content.

Is The Day The Cosmos Fell Worth it?

Honkai Star Rail The Day The Cosmos Fell is generally considered worth it, especially as a free-to-play (F2P) option for Erudition characters. It is a readily available 4-star Light Cone designed specifically for characters who follow the Erudition Path. Its ability, Stratagem, provides a consistent ATK increase and a significant CRIT DMG boost when attacking multiple enemies with the corresponding Weakness. At Superimposition Level 1, the CRIT DMG bonus is 20%, increasing to 40% at Level 5, making it particularly effective in battles with groups of enemies.


This Light Cone synergizes well with Erudition characters who specialize in AoE damage. Since its effect is activated by attacking at least two enemies with Weaknesses, it naturally benefits characters who can consistently hit multiple foes, such as Herta, Himeko, Jing Yuan, Qingque, Serval, and Argenti. These characters have skills that maximize the potential of Stratagem, ensuring frequent activation of its buffs in multi-target encounters.

Honkai Star Rail The Day The Cosmos Fell is also relatively easy to obtain, as it can be purchased from the Forgotten Hall Store for 200 Lucent Afterglow. This makes it a reliable Light Cone for players who engage with Forgotten Hall content. When compared to other 4-star Light Cones, such as “Geniuses’ Repose”, the key difference lies in their activation conditions. “The Day The Cosmos Fell” requires attacking multiple enemies with Weaknesses to activate its CRIT DMG buff, while “Geniuses’ Repose” triggers upon defeating an enemy, making the latter more flexible in single-target scenarios. Some comparisons suggest that “The Day The Cosmos Fell” can outperform “Breakfast” for characters like Himeko in multi-target battles.

Despite its strengths, this Light Cone does have limitations. The CRIT DMG buff is conditional, meaning that if there are no multiple weak enemies, this part of the ability will not activate. However, for players looking for a strong, F2P-friendly Light Cone that enhances AoE damage potential, Honkai Star Rail The Day The Cosmos Fell remains a solid choice, providing a consistent ATK boost and a situational yet powerful CRIT DMG bonus in the right combat situations.
