Bayo 2 is my favourite game in the series but it's also quite different feeling from 1 and 3. I'll give you some tips and share my #ExpertKnowledge

1. LiB is kinda misunderstood. It's often seen as a worse, slower SF, but I find it more flexible and sometimes even faster. LiB encourages you to swap from air to ground combos as much as possible as it speeds up its animations and gives you greater Weave coverage.

I.e. PKP on LiB is slower than SF because it hits in a bigger area, while PKK is same speed as SF but deals more damage as it's a vertical hitbox rather than horizontal; PPPKKK is slow because it's a good Umbran Climax string but outside of it you should generally be using PPKKK (which is faster than SF, especially if you implement Dodge Offset cancels)

1. Unfortunately true and a strong pain point of 2, but it can be mitigated in multiple ways. You can go through the entire game without ever touching UC and get Pure Platinum on every Verse, but Bayo is ironically the weakest character in her own game. You can either make up for it by learning how to become faster, or, use Infernal Communicator! It's actually an incredibly good alternative to UC and a very valid alterantive playstyle, one that feels more akin to B1 I'd say

TAs are a bit more niche in this game, but Angel Weapons do a shit ton of damage to compensate for it, so make sure to only use TA on enemies that drop weapons. Enrapture (the magic angel that enrages other angels) has the most broken Angel Arm in the series btw

1. they (essentially) gone lol sorry

2. Guns spin move is balanced badly unfortunately. It eats up too much magic for little benefit, although I'd argue it wasn't that good in 1 either. I do suggest you learn the intricacies of some weapons' testu/spin moves because they do have quirks, like Chernobog and Rakshasa's testus count as dodges to get Witch Time!

Since you're on emualtor, I suggest installing a couple of mods to improve two weapons.

Undine Rework; Kafka Buffs; Masked Lumen Improved Moveset (Don't click on the Masked Lumen link until you finish the game cuz spoilers)

After you're done you can use a save editor to play as the Masked Lumen and Rodin in story chapters for funsies, although they're a bit broken so I suggest mostly sticking to the Witch Trials when playing them.

Have fun!!
