Why do even new players aim for stuff that are targetted towards older players? As already stated by many, the event quests only require until floor 25 for both towers which doesn't really require a Miu so no Pay2Win excuses.
If you started playing VF a couple of weeks ago and you expect to be able to clear the whole event, no offense but you're pretty delusional. Veteran players have problems past floor 30 too even with event units.
Yap, agreed. non event 5* will at most get you to level 29 of Unity. From 30 onwards, better to have events unit. 31 to 34 is easier than 30 though (I think because floor 30 is gem rewards). I ran a 2 Miu team and even with adding 1 Miu Merc, still can't clear floor 40. And my eq is +15 purples... so think it really meant to be a challenge and not meant to be cleared by everyone.
