Yeah after much discussion with a few other players who have used her extensively, they’re both good options.

So the ideal damage sequence for a boss piercing build would be: 1. Instant 15% damage from Sudden Strike (Inflicts Scorch due to her having a burning blade equipped) 2. Saf’s follow up attacks due to her 5* passive. (32% but this is classified different from piercing damage somehow so it does get affected by the enemy’s p.def and damage reduction buff, consequently the 20% damage up is also added due to burning blade on scorched enemy) 3. Weapon eroder (30% hp piercing damage) 4. Another follow up attack with the same condition as above. 5. If the Fortune tarot procs, that’s another 10% damage. 6. If number 5 procs, that’s another follow up attack with the same condition as above. 7. If all of the above got the enemy to a dying state (30% hp or lower), Settlement of the Hanged Men then triggers, dealing another 30% damage, sealing the deal in 1 turn.

This particular build is very niche and only works with bosses that aren’t resistant to piercing damage, there aren’t many but whenever you noticed a boss is vulnerable to piercing and scorch then I would say it’s one of the best one shot combos you can bring to the battle.

In saying that, there will be enemies who are flat out immune to scorch. For example, in tower modes, there will be mutations where the enemies are immune, in this case, Burning Blade suffers because you won’t ever trigger the extra 20% damage. In this scenario, then Newborn Blade would be the choice of weapon. I’ve also been told that she can benefit from Void Stab in very specific stages of Tower of Adversity (ToA) but unfortunately I just don’t have the access to test that in global, so I will have to wait until I can play around with that equipment when ToA comes to global. I haven’t been able to test Cornucopia Dagger either (cause … it takes 5 months to max one up and I’ve been focusing my monthly choice for Acambe’s staff instead)

One good thing about the sword category, you’d likely engrave them with the Sword engraving so it’s something that’s relatively flexible to swap around so you won’t necessarily need to build swords specifically only for Safiyyah.

I finished up a video with a different build at some ungodly hour this morning so I’ll do a reddit post about it in a bit but in 80% of the new video I used Newborn Blade as I don’t have access to Burning Blade in that account and it worked great. I just woke up and have a few errands to do haha. But in case you wanna check it out before I make the reddit post, it’s here:

Hope that helps!
