I have two Fallen Robin. Both are +SPD. One is -DEF, the other is -HP. Since I don't plan on keeping him on my core Arena team, I'm planning on building the -HP one and using the other as fodder.
However, I'm not sure which skill is better to fodder. Vengeful Fighter is amazing, but I already have an extra W!Tharja ready to fodder, and I don't have any armored units that would want this skill (except maybe the LA units, but I was suggested to hold off on that). Ward Dragons is a one-of-a-kind skill, and it allows me to have Fortify and two Wards on my Dragon Emblem team which consists of Nowi, Fae, Ninian, and (now) Fallen Robin.
I am having trouble deciding on what to do and would appreciate any input you guys have.
I'm more biased to Armor Emblem but at this rate we could all just consider Armor and Dragon emblem to be the same type of "Emblem"
That being said it's just up to your taste personally, if you like armor emblem more there's plenty that loves Vengeful fighter, while if you like Dragon emblem more you can give Ward dragon to your top 4 dragons.
