★ INTRODUCTION ★
With the v7.0 update, the new weapons [Bloodied Casket] and its PRI-ARM [Bloodied Casket: Tough Love]
will be added to the game.
In this guide, I will explain the weapons, compare them to other weapon options and talk about their usefulness on other Valkyries with similar use.
These weapons are the signature equipment of the newly added S-rank Battlesuit [Lunar Vow: Crimson Love].

★ WEAPON COMPARISON ★
Test Runs
Note!
All following tests were done using the signature stigmata set of [Lunar Vow: Crimson Love], [Sweet Dreams].
All other team members are using their signature equipment.
Lunar Vow DPS
Lunar Vow Support
Mobius & Griseo
Rotations
Usable on other Valks?
Yes absolutely!
For both Mobius and Griseo this weapon is the newest best Alternative if you miss their signature gear.
It provides a lot of Lightning DMG and also increases Bleed DMG, so it works very well for both of them.
★ GAMEPLAY ★
★ CONCLUSION ★
Is it worth to get this weapon?
Yes for sure!
It is the only cross with lightning support capabilities and very strong self buffs.
The best alternative would be the old and trustworthy Oath of Judah but only because it deals a lot of DMG not because of any type of support.
The DMG loss isn't too big but I would still say try to get the weapon if possible.
Overall she doesn't lose too much DMG if using Oath of Judah so it is definitely a good option
That's it~ 
Thanks to every captain who will read my guide and I hope it will be useful to you! 
As always I wish everyone lots of fun in Honkai and may Ai-Chan bless you with luck in the gacha!
