Moon Halo essentially dictates your strategy and what your playstyle is centred around. There are 4 types - basics, ultimate, QTE, and evasion. I've only just unlocked the ultimate one today, so still not used to it yet. It's a pain to kickstart ultimate MH since you can't charge the meter unless you ult. Well, it'll get better with time and practice, and more OP effects are unlocked at higher levels. For instance, at Lv15 MH ult CD gets halved. #HonkaiImpact3 #APHO2 #Ruins
