Ineffa really makes a huge difference as last time without her I had to use Skirk team to brute force this same boss. Now I just rolled her and I'm amazed by how she literally elevates my C1 Flins to my second best dps just behind C2 Mavuika, with an only 2 five stars team, even surpasses my well invested C2 Neuvilette premium team. I can say she's much more important than Columbina in his team and for anyone who feels bad not being able to get both this banner, with Ineffa, Aino is more than enough.
First time my Flins team clears Dire SO thanks to Ineffa.
