Grants 2 skill EXP to specific revived event units.
Bonboris for each Revival Event are unique and only meant to SU the revived unit, and thus cannot be used to SU other units unless their skill's name is the same.
Example of how Bonboris work
For example, a Bonbori dropped during Nagi's revival will have the skill "Secret Pill" while a Bonbori dropped during Paula's revival will have the skill "Heal Magic Plus".
You can use the Bonbori dropped during Paula's revival for Eterna since they have the same skill while the one dropped during Nagi's revival won't have an effect.
