the pity % broke
it wasn't saber. It was a Luke. A character I routinely forget is even in the 5* pool. There were 2 other red which, to add insult to injury, were a 4* Caeda & a 3* Cain.
At least I didn't have him, I guess? and he's not been reran...ever, actually, so pity breaking was his only real shot. He's also +Attack/-Res which is pretty good for him!
*sigh* I'll get you some other banner, red fjorm. Some other banner.
Actually I got curious, here are the 5* exclusive units who have never gotten any sort of rerun:
Luke
...That's it. Saber used to be in this category until literally this banner. All the other ones are recent units (brave, brave redux, half of nohrian dusk) who haven't had a chance to get a rerun. If you start excluding Legendary banners or go looking into dates and such, it'd be a longer list but that's still almost impressive. Still feel bad, though.
