Columbina or ineffa

I'd say Ineffa first, Columbina will rerun before the end of the nod krai cycle.

Ill break it down for you:


If your not going for any other Nod Krai characters you can pickup either Ineffa or Lauma (Fantastic standalones since introduced outside of Nod Krai but are BIS slot for two of best two teams in the gamr) by themselves or skip entirely


Nod Krai as a whole is highly tuned and ultra specific without alot of leeway.


Columbina is a like supercomputer for Nod Krai chars (outside of Nefer which ill get to in a second) now older geo characters can profit with a new geo bonus but it still gets outed by Bineffa plus xilonen . or C6 Illuga + Zhongli for Zibai. Because its having two superconductors together for the reaction or one that doesnt inerfere and keeps the ball rolling and Xilo mogs non C6 Illuga and is the ultimate setup support for older geo carries..


Lauma look I like her but she has all the real estate when it comes to Lunar Bloom no one on the roster even comes close.


The quickest way into it is to:


1 Commit to one team


2 Pickup really solid chars as standalones


3. Get Both and have the best core in the game since their elemental identity is extremely flexible for anyone. Yes you wont get the best Nod Krai team objectively but more of your roster can utilize the duo.
