The biggest tip I've learned about the DLC
Only area with gun enemies ruining my defense upgrade and in general just the worst! Thank goodness you can avoid it.

Small guide
Make a Ninja Talent Corrin (I did +strength -speed but doesn't matter for this, apothacary also works.)
Make sure to do combat with Felicia in the prologue chapters to get an instant C support.
Focus marrying her once your actual route starts, I did conquest lunatic and was able to marry her by chapter 11. If you have trouble killing things, reclassing to strategist or using a felicia's plate from renown rewards can help a lot, but it's not needed whatsoever.
Use a partner seal on her to go mechanist at level 10 or 11, partner seals are basically not contested at all this early so shouldn't be a problem
Do Kana's paralogue when you are close to level 15 on felicia, Kana's paralogue gives a lot of XP, so getting 2 or even 3 levels here to finish getting replicate is very easy, and Kana will re-inherit skills at the end of the chapter so you can obtain replicate during and then have them gain it when the chapter is over, just MAKE SURE replicate is felicia's bottom slot when you kill the last enemy. This only matters if you want replicate kana as soon as possible, but I found it a fun trick.
Reclass Kana and Felicia to whatever you want from here, I went master ninja with felicia to get shurikanfaire and strategist with kana for a replicate healer. Boom, you have essentially two extra deployment slots for the rest of the game, online by chapter 12. They will be squishy...but not really a deal breaker in conquest specifically tbh.
Note: This also works with jakob if you prefer female corrin!
