Legends Ch 1A

This unlocks after ch 4 but has a 12 squad cap, how many squads do you need to handle it and what level /main map is recommended?

In my experience (only did it once mind you) the legends chapters tend to be a lot harder than the main story when you unlock them, I managed to do 1A around chapter 10 or 11, but this was on NG+. I'd wait with most of them till around chapter 18 or 20.
Legends 6 is easily the hardest map in the game as well, though at time of unlock you should have most good tools.

I find that story-wise the legend maps feel very weird if you play them right when they come out. i.e. the Penderghast's Folly mission will spoil you on a plot twist that occurs after chapter 12 if you play it before that.

They also tend to be much more difficult than the missions you play when they unlock.

(I personally couldn't do 1A until chapter 7 or 8 I think.)

I'd say maybe wait 3~5 missions after you unlock them to attempt it.

Thanks all!

The legends DLC missions can become SIGNIFICANTLY harder the further down that list you go.... that friggin last mission has 4 units of 3x dragons with an oracle at a power level of 15K right at your doorstep.... then ooooooooodles of hit and run cowards of decent power to the right and a Behemoth kennel to your left... South is probably easiest... it's just an artillery/archer chokepoint....

I tried it straight after I mett the unlock requirements but didn't even come close to doing it within the turn limit xD

I technically was able to win 1A as soon as it unlocked, but it was messy. I didn't collect 2 timed chests, and the guest unit did most of the heavy lifting, thus getting less bonus exp for my units. Ultimately I reloaded to before the attempt and plan to try again later.

As a general rule I would suggest not doing Legends chapters until you have enough good squads to fill the max they allow you to use. Any exp earned by the squads that are forced on you in each chapter is basically lost (plus keeping them alive is usually a requirement) so you'll want to use only your squads to fight, and as mentioned above the difficulty level for these is quite high. You definitely don't want to miss any timed chests as they are almost all unique artifacts you can't get anywhere else (though some of them aren't that great).
