(JP spoilers!) New unit analysis post
ex fes koakuma (A6&)
- great lw damage. has hihwm and ikagura/c3 shion as good options; wide killer range (mainly human, youkai, god)
• aoe sc seems to have high damage. p0 killers suck though (SDM, miko, magician, Devil, vampire, great youkai (lol), makai)
really good self buffs:10 yin atk 10 crit atk 3 yin def up 2 yin def down 9 crit acc for some reason (12 if you factor in crit eva down)
S3 is 2T (3 crit atk and acc to self, 3 party yin atk). just elevates her self buffs even further.
-really selfish. girl is support btw
-no acc lol and seems to be p hungry just like ex sakuya
-bad breaks. 3p with only 3 aoe burn.
to sum up, she is a very solid star nuker with good self sufficiency. don't be confused by her class though, girl isn't a supporter in any way. just treat it like an additional niche as in she can run the crazy support cards.
it's worth noting that this koa is kinda held back by external factors: she has crazy niche overlap with prae where koa doesn't have anything special over prae, plus star is the most powercrept element of all, so generally speaking koakuma is very easy to replace.
as for how she compares to other ex fes, she is definitely top 2. sakuya still has a more consistent kit plus is harder to replace. though that isn't saying much as koakuma is essentially rfes, the best rarity in the game, so the opportunity cost is just insane.
