Oh yeah, I think another reason I'm enjoying her companion story is because it involves Rover's past and Black Shores

Took me some time to figure out how to score in this combat event. I notice it's mainly about basic attacks (makes sense, since Camellya's banner is running) and Havoc resonators. It's interesting that some hate the event on Reddit because they think it's only to promote Camellya. I have her but I'm still not used to her so that doesn't make the event any easier for me. 

Anyway, I think it doesn't have to be her... you can still use other Havoc resonators and anyone that make use of basic attacks. In Jiyan's case, I ended up using less Resonance Liberation skill because it takes too much time and the attacks aren't considered basic attack damage. So.. Jiyan isn't really effective in the higher difficulty stages. Xiangli Yao is great. I might experiment with Encore & Aalto later. Sometimes I even skip using the echoes or only use them when swapping characters. Oh yeah, sometimes I also skip having a healer because I just want everyone to give high basic attack damages. 

Amazingly, I've finally hit the inventory limit 2000 (several times, even!) recently. Especially after the double drop event for Tacet fields. I've started to mark them discarded more closely and frequently because of this.

Also, something I just realised... yes, building characters and upgrading weapons takes a lot of resources but I think building echoes will be much more expensive than those two on the long run. Especially when you can't predict what substats you get. It's also not easy to get the materials (in my case, it's the echo xp... my tuners are fine, at least for now). I always end up just going "eh, good enough" with mine lol...
