Rath’s Review

Rabbit’s Review


Everyone thought it would be Oberon to powercreep Merlin… no one expected Koyanskaya, like the Spanish inquisition!


So when’s Merlin but with zero survival. She’s great but might not be jsuitable for longer battles like Boss Rushes. She reminds me of Skadi.

that first line
it should be 500% chance to drain hp

Jesus Christ, she’s gonna be disgusting with someone like artoria whose skills all have 5t CDs :fgo_deadinside:
Double Koyan + seiba


The first truly powerful cardtype-specific support who isn’t a Caster (sorry, Okkie).

With those hitcounts, passives and starbomb she’ll also generate a load of stars for the main DPS to use, and recharge her own NP rather fast as well.
She’ll need Castoria or Merlin support against bosses that insta-charge their NP on bar break and stuff, but for farming and damage race content she’ll be a monster, especially if the main enemy has Human trait and/or attribute.

Himiko i would say is rather powerfull too, and while she can work with any team, she is mainly buster focused.


Fair enough, forgot about her. Though with 2 out of her 3 skills being selfish and her main team steroids hidden behind her NP, she’s certainly not as easy to use (especially for farming, since she provides no battery to other servants).

Yeah, Himiko doesn’t really count here for those reasons. I think a lot of hype that isn’t tied to Buster Crit is related to her Castoria cockroach meme, which is whatever.

Double Vitch + AA. Double stacks his powermod and atk buff :fgo_tamamo:


That was my first thought, like:

Not only can she make him get essentially 6 turns of crazyness but also help his Star Gather when said crazyness is on cooldown.


This skill-based 2T CD reduction on a big buffer is going to open up a lot of fascinating shit.


Vitch isn’t dethroning Castoria but hot damn, has she made Buster Memes A LOT more viable.


Can wait to see xnaya video about Double Vitch System


Gawain with DKS + Atlas could potentially allow a meme-y 12T full buffs~

Barghest coupled with Vitch and BB Summer seems like a fun meme too.


I think I’m in love with these skills.
I know I’m in hatred over her art, she has so many good story costumes and they give her this? :fgo_badciv:

But targetable battery :ballot_box_with_check:
CD reduction :ballot_box_with_check:
Targetable trait damage :ballot_box_with_check:
Star bomb for crits :ballot_box_with_check:
Targetable Buster AND Crit AND gather weight high enough for Berserkers even :ballot_box_with_check: :ballot_box_with_check: :ballot_box_with_check:

Party NP charge via NP :ballot_box_with_check:


She really does open a lot more doors. DW has been expanding the possible gameplay repertoire, tho at the cost of over-equipping the newer servant kits with effects~

They’re just waiting to drop all her costumes in the RP shop :fgo_gudako:
