Worth building?

All -Atk?! Wow that's sad.
Not really worth building anyone, and sadly not really good fodder outside of firesweep sword.
Just keep them around. Also I wouldn't recommend saber if you any other 5*stars due to exclusive holding Slaying Edge+ and Shield pulse. But if you don't have any good 5*swords, than sure

All of these are garbage except for maybe Saber.

Right here. This is precisely the reason we need an IV reroll system.

Keep them all for future merges if possible, they are all still perfectly usable, Soleil in particular is good with any IV, and she appears at 4 star so it will be easier to get a better one in the future

FIrst off. I’m sorry for your sickness of the -atk bane. Hope it gets better. Leif does have the s drinks and you could fodder them off. Ryoma could be used as +1 fodder as well. Best wishes

In comparison i have had some what the same problem but i was trying to get leif but ended up with
*b roy
*ayra
*ryoma
*saber
*2 reinhardts one useful one
*f_cking leo
So all my saved orbs are gone plus the orb pack and the free 20 orbs now im just?

Ask for your question i would build saber,maybe fodder off F sword and keep the rest
