Chrom build

Inspired by Sir of Coffee building Roy, I've decided to build Chrom in honor of me enjoying him in smash ultimate.

I figured I'd make use of spectrum bond and the bond seal for +9 to all stats next to an ally. A spur seemed like a pretty good choice to go with bonds, and reciprocal aid can allow him to heal allies thanks to Falchion's renewal effect and aether giving him some self healing. Chill def for more damage. Any possible changes or recommendations?
