It is possible to strengthen a demon’s stats by using 「Mitama」 demons or 「Mitama Extract」 item.
※This can only be done upon clearing story Chapter 5.
「Mitama」 demons appear on floors 41 ~ 50 of the Aura Gate and can be obtained by negotiation through Demon Talk.
Also, upon defeating 「Mitama」 demons, 「Mitama Extract」 will be dropped.
The strengthened stats differ between 「Mitamas」
★2 Ara Mitama ：St＋2, Ag＋1
★2 Nagi Mitama ：Ma＋2, Lu＋1
★2 Kusi Mitama：Ag＋2, Vi＋1
★2 Saki Mitama：Vi＋2, Lu＋1
Stats increase by 1 upon using 5 「Mitama Extracts」.
The maximum upgrade capacity for each type of stat is 10.
The maximum total stats that can be strengthened is based on the base rarity of the demon.
