Merge or Fodder Lyn?

merge, you can get galeforce from cordelia

I'd try to fodder off Galeforce before merging. There are some experimental builds that I'd like to try, but spending 20k feathers for an experiment isn't always something I'd like to do, so having a unit that comes with the skill, and you didn't have to spend 20k feathers on, is nice.

But, of course, if no one wants Galeforce, then merge.

Fodder, Galeforce is really useful and chances are merging your lyn won't change how you play the game, but if you give a really powerful unit galeforce, you could have better options. If you can't decide, then wait until something in the game makes the decision obvious for you. I saved a brave lyn like that for almost 4 months then I got a +atk siegbert out of nowhere.

I would probably spend the feathers for the galeforce fodder
