Added a new power benchmark, Atomic Weight. Prime-of-life stat multipliers also received a major buff, and reincarnation bonuses and SNS sharing were revised.
New feature: Atomic Weight
"Atomic Weight" is an estimate of your overall strength, calculated from your character's abilities, the growth of your memory fragments, your bonds with allies, and your walking effects. Every stage now shows a "clear guideline" value. Use it as a reference when a stage feels too hard, or when you're not sure which stage to start from after reincarnating.
Atomic Weight is only a guideline — your actual strength still depends on your fragment combinations and how you use your skills.

A LV99 memory fragment can be returned to LV1, carrying over part of a chosen ability as a permanent trait. The more times it reincarnates, the higher the inheritance rate.

Selecting a stage now lists your personal best for every Lv. Tap a Lv with records to see its top 10 entries.

If the summon you are about to make would exceed your capacity, a warning now appears beforehand. You can either swap out a fragment you own or decline the new one entirely.
