Saw your questions about a potential Boey build, and I would say with his natural high defenses and his prf letting him counter close ranged units (which aside from dragons are all physical units), stacking his defense is the best option. I think the best C choice would be Joint Drive Defense or a rouse/oath skill that buffs his defense. As for a blessing, it completely depends on what you want to use him for. He makes a really good counter to units like Ninja Lyn, Legendary Chrom, Yuri, (1)
Fallen Edelgard, and Ash, who are pretty common meta threats in several pvp modes, so if you are having problems with any of them you could just give him a blessing based on where you run into them the most. (2)
Thank you for this! I don’t play PvP all that often, so I don’t often build units beyond their base kits or really know much about which skills are good for what. So this is really helpful!
For anyone curious what the other recommendations for a Boey was, here are these two posts by @emblemxeno
