Some new math is up for Lucia
https://youtu.be/gI2mYXdyaWg?t=323
Very easy to play:
EX special + skipping to a Basic = maxed Lucia bar.
But there is an alignment issue.
Lucia's EX special intervals will be 8s +8s +8s +8s = Every 32 seconds
Moonlight Lullaby only lasts 25s, this means you will only have 78% uptime for the 4p disc buff.
If you want 100% untime, you will need enough Energy regen to kick off 2 EX specials every 32 seconds.
That means 1 EX per 16 seconds. That's going to require 3,75 Energy Regen.
140% ER, which is doable:
60% from slot 6
20%+20% from swing jazz + moonlight lullaby.
50% from Gameball, or 40% from her Sig will also be enough.
