The Day The Cosmos Fell is a good Light Cone for Erudition characters that specialize in AoE damage and attacks. The CRIT DMG buff can easily be obtained by attacking multiple enemies with their Weaknesses.

Is The Day The Cosmos Fell Worth It?

Great F2P Light Cone Option

The Day The Cosmos Fell's effect is similar to Geniuses' Repose, but instead of defeating an enemy, the wearer needs to attack multiple enemies with their elemental Weakness to obtain the CRIT DMG buff.

This Light Cone is a great option for Erudition characters if you don't have Geniuses and can shine in situations where there are multiple enemies with the elemental Weakness of the wearer. Geniuses is just way more flexible since it's not locked to multiple enemies.
