I'm playing on hard mode again and have finshed 3-10.
In the base before 3-11 you have the Greil's Mecenaries and Crimean Knights together, so you have access to the "paragon" and the "blossom" skill.
I actually have never thaught about this skill combination.
The main problem is that the units except for the Laguz have not enough capacity to get both skills. So you can give the blossom skill only to a character, who has a "free" paragon skill. Geoffrey leaves the party till 4-5, so the only one contendor for this combination would be Astrid. Seriously I never have trained her, because her growths are pretty bad. So much more I think, it could work with this skill combiation.
My aim would be to give Astrid many great level ups as possible, so she can cap maybe some stats in level 11-13 (guessed). I would promote her with the mastercrown early as possible.
I also know that the blossom skill does not always guarantee great level ups.
Has someone had good or bad experiences with my idea?
