Something Irreplaceable Best Characters

All Best Characters

Character	Explanation
Clara	You'll want Clara to continuously deal Counter-Attack damage. Something Irreplaceable provides Clara with some DMG boost and healing every time she is hit. Hence, Something Irreplaceable is the perfect Light Cone for her playstyle.
Arlan	Arlan needs the ATK stat buff that Something Irreplaceable provides. Also, Something Irreplaceable's self-healing gives Arlan a safety net since he constantly sacrifices HP to deal more DMG.

Other Recommended Characters

Other Characters
Blade	Hook	Trailblazer
Imbibitor Lunae	Jingliu	Firefly
Yunli

Something Irreplaceable is generally a great Light Cone for most Destruction characters due to its high base stats. Something Irreplaceable ATK increase works well for characters like Hook and the Trailblazer since their abilities scale off their ATK stat.

Destruction units like Blade will not benefit from the ATK increase since they scale off their HP stat.

While Something Irreplaceable's self-healing is good, it does not work all the time since the wearer needs to be attacked!

Is Something Irreplaceable Worth It?

Not Worth to Use Undying Starlight

While Something Irreplaceable is the best Light Cone for Clara and Arlan, we do not recommend buying it from the Starlight Exchange Store.

If dealing damage is your main concern, On the Fall of an Aeon is a perfectly fine F2P 5-star Light Cone for most Path of Destruction characters.
