Who did you ally support with Fjorm?

Ryoma is a good choice. After all you want to use the blessings on units that support the legendary hero, not the other way around because in order to gain any use out of blessings you need the legendary hero in your team 100% of the time. Ryoma is just what Fjorm needs to get rid of green units.

I chose Arvis. Plus atk ploy as his seal he debuffs atk,def and res. So Fjorm takes less damage(-atk) and can do more damage(-def), and if there is a green unit Arvis takes charge(-res).

I chose B! Cordelia. I have a firesweep build so the speed helps Cordy, and she benefits from having a tank around to bait enemies, reposition her away, etc.

I like the suggestion of Arvis though - he’s on my Arena team with them right now (with P! Azura as fourth) and they all work very well together.

currently supporting P!Azura because they happen to be on the same team for AA. I conferred Eliwood and Lukas. Obviously Lukas is not a strategic choice but he is my favorite unit so he gets first dibs.

B!Cordelia. I used the Water Blessing on her for the SP and figured that I may as well support them and keep them on the same team.
