unlocking the ultimate needs multiple copies (dupes) and awaken them(violet stars) some takes 3-4 copies before unlocking their ultimate, kinda hard thing to unlock tbh 🙁
3 ordinary skills
+1 synergy/combo trigger
+1 defensive/counter/heal
+1 ultimate(others had 2 idk)
I will follow up a video for 3 star units, since units like Rin are only 3 stars
