Did I break the legendary banner?

I'm at pity rate of 15% no 5 star yet, around 100ish dry

I just got a LEphraim at around 200 orbs. My luck is still average after the last day of the new years banner where I got 2 NY Azuras and a NY Takumi in the same summon

That's a 5-Star roughly every 20 orbs... Absolutely amazing luck!

Don't fret too much, as you still have a little under 3 days to continue trying if you wish. Also, Genny is available in the normal summoning pool, so you might get pity-broken by her one day, or she might be a focus on an upcoming banner.

I thought this banner was super lucky for me because I really wanted H!Jakob, and ended pulling 2 of him! (One was +Def / -HP, which is amazing for more mixed phase tank builds.) Along side him, I ended up getting L!Grima (+Res / -HP) and Genny (+Spd / -Res)--other heroes that I wanted with decent to good IVs to boot!

In total, I want to say that I used ~160-170 orbs for this banner, and getting four 5-Stars that I really wanted and didn't have is pretty great. The only hero that I still really want would be PA!Inigo, but I might just consider stopping here and saving orbs again to avoid ending up with high pity rates.

With 300 F2P orb, i only pulled L!Lyn +def -atk and PA! Inigo +hp -spd. I already have a +spd -hp PA!Inigo, don't care about L!Lyn...
Just wanted L!Robin, H! Jakob and H! Henry...

So yes, i think you have been incredibly lucky for this one ^^

It hurts for me to hear it, since my luck with this banner was garbage, i had to spend 190 orbs to get -atk +res Inigo, -Atk +Hp H!Henry and -spd +Hp L!Grima.
So congrats, i wish you will be as lucky as right now.
