★ Weapon comparison ★
Okay, okay. Let me say something.
5000% additional multiplier as Ignite DMG is A LOT.
Also, please note multiple Rudder buffs are team wide buffs that also activate when using it on Ai-Chan.
And those don't stack
☆ DMG comparison ☆
(Just get that weapon tbh)
Sirin used her signature Stigmata, Ai-Chan and Herrscher of Truth used their full signature gear.
★ Gameplay ★
*cutely steals Inaris videos*
★ Conclusion ★
Is that weapon worth getting?
Well, definitely if you wanna use your Sirin.
Without she's pretty much useless.
It's like...
she's completely free except for her weapon and the weapon has a max pity of 50.
Lemme list the only situations I'd recommend skipping Sirin.
- You have a well built fire team with Spina Astera or Herrscher of Finality (and maybe Mobius too), while other teams lack a lot.
- You don't play for meta and don't like Sirin. Why did u read this then though
- No HTR, not planning on getting her. Thats a pain.
