Zuzuska's FIRE Diamond Evaluation

I personally love my Diamond BD. She's sitting at level 40 right now and lets me easily carry even at high streaks. Her damage gets pretty insane if you get a few procs of her passive. By the time the self bleed would become a problem the enemies will already be dead.
Also pairing her up with a Surgeon General helps with the self damage if you're worried about that.

 

Going to copy paste from Firefly Discussion

I believe in Firefly. Easy Diamond.

With the new durability boost from Grudge she's going to be very difficult to burst down from 50% even with BB3s, which lets her take more advantage of enrage's damage boosts, and she even has impressive meter control with her own BB3.

She may be considered off-meta, but the way I see it she's quite versatile and statistically beefy now.

I feel the boost in HP and damage she gets from Diamond actually benefits her more than most other diamonds; though I don't think she's too close to the top of the priority list, I personally think she at least deserves a spot in Decent.

 

I was just about to say this lol. Firefly was already a surprisingly effective diamond w/maxed tainted blood imo, but now, in this brave New "post grudge buff'd" world we're living in, she's one of the biggest defensive threats in the game.

Sure, she has to compete w/buzzkill (who can now shrug off a bb3 as well as kill things) for resources, but the same could be said for sheltered and primed.

My top 3 fire diamonds post 2.7 would be:

1. Harlequin
2. Sheltered
3. Firefly

 

I'd like to question Red Velvet choice in Drift Battles.

So far from my experience node difficulty is Boss -> Armour -> Stun -> Immunity (questionable) -> rest.

For boss node due to elemental advantage requirements she can only reasonably counter AF.
For armour node her SA has potential for locking defensive SAs but does nothing against the modifier itself. IMHO here she loses to Rusty in most cases. Case could be made for countering Bloodbath though, but you'd still have to rely on stacking up on Chaos Banish and Middle of the Sphinx for the fight itself.
For Stun node she's in the usual place compared to other anti-defensive SA fighters.
For immunity node she's just your another Elisa.

IMHO she's only as good in rift battles as other potential fire candidates are bad (or at least bring no utility to the table).

Her place in drifts so far looks like "i'm not made out of diamond SKs, so I'll have to get by with alternatives when applicable".
