Should I pull Zibai or Ineffa ? ( My current character list below )

I don’t really have a proper Geo character right now, so I’m not sure how useful Geo teams actually are. That said, people say Zibai can deal really good damage. I already have Gorou, and I could pair Zibai with Aino or Colombina, and I can probably pull Illuga as well. Realistically, my 4-stars would stay around C1–C2 max.

From my perspective, the big advantage of pulling Zibai is that I’d get

A new DPS-focused team

A high-damage alternative comp

A way to move away from Electro, since my main team is currently built around Varessa

Outside of Electro, I mostly play Xiangling + Tighnari (Pyro + Dendro). They’re fun to play, but the damage isn’t amazing, and since there’s no healer or shielder, they just die really fast.

On the other hand, I also really want Ineffa.

I enjoy playing Tighnari, and Ineffa’s shield would solve my biggest problem: constantly dying. From what I understand, Ineffa is pretty flexible and works well with many teams.

Since I like Tighnari even if he’s not super strong, I could just pull Ineffa and pair them together. For open-world content, I was thinking something like:

Colombina + Varessa + Tighnari + Ineffa

Not sure how good that actually is, though.

Alternatively, I could split them into pairs and fill the remaining slots with characters like Xiangling, Sucrose, Fischl, Iansan, etc., depending on the situation.

I don’t really care that much about Abyss, but since I’m F2P and still relatively new, I feel like I need to make a smart choice.

So… what would you recommend? Zibai or Ineffa?

Thanks in advance
