Use her for last evo, it saves you 5 otogi stone. If last evo already done, then level up skill.

From discord:
11:55 AM] Azalea <3: Question: How should I effectively use my dupe unit skills?
A: Level-up first the original unit's skill to lvl 02 then use the dupe skills (for lvl 03), then add blue/pink fairy essences to reach a higher chance of success.
Lvl 01 > 02 = use green/blue fairy essences
Lvl 03 = use skill dupe
Lvl 04 = skill dupe + 2-4 blue fairy essences, or 5 pink fairy essences
Lvl 05 = 2x skill dupes + 2-3 blue fairy essences or pink fairy essence/s
Lvl 06 = 5x skill dupes/rainbow fairy/test your luck
