Holy shit...
When was this added? It looks amazing like this! I can't be 100% sure but it feels faster too. This is a game changer, it looks so smooth and good...
Also, regarding your vid - that's nice damage. I really like Melusine, but for me the grinding is all about efficiency in this game since it's always a manual grind. Being locked to a specific mystic code and having to do a swap and press so many buttons would make that feel awful during grind events. Back when I rolled for the buster loop meta characters, I was informed that we'd get 90++ nodes that arts looping can't 3 turn, but until we get that, I'm sticking with my 2x Castoria/Summer Kama.
I mean, I'd probably do less button mashing if I stick to Space Ishtar/2x Castoria...but that's the team I've been using ever since Castoria came out (and before that I used Spishtar with 2x Skadi). Needless to say I'm pretty sick of seeing her NP at this point lol. It's nice to use different stuff now.
Also an advantage for Buster looping is not having to worry about NP refund. So the weird waves of less than 3 enemies (or waves of Assassins/Berserkers that give less NP refund) don't matter any more.
Before I got Oberon, I was using 2x Light Koyan/Morgan with Aerial Drive CE/Waver (until I got Reines, then she replaced Waver).
EDIT: Random factoid, the reason I refer to Melusine as "Blue Melu White Dragon" is, aside from her obvious blueish-white color scheme, the fact that I got her to NP3. And BEWD was always my favorite in Yugioh lol.
