What build for Gray?
A long while ago I pulled a Gray pity breaker while going for Festival Micaiah, and always wanted build him, as SoV was one of my favorite games. Problem is, I have no idea what to do. Just recently on all these free banners, I pulled both a five star Silvia and a Karel, and decided it's finally time to build him. Trouble now is I can't decide what's better; trying to remedy his res with mirror blade and going for a mixed tank, or using Wo Doa and going for purely defense, to make him a better tank, but super susceptible to dragons he might otherwise stand a chance against. So what do?
Well, thing is you either want to specialize in one defense, to the point where you're taking little damage from that half of the damage spectrum, or you make him fast enough to avoid doubles and then he can do mixed bulk. Because in trying to salvage his res, you will end up with two decent but not stellar defensive stats, and if he's getting doubled, it will likely result in him not being that tanky. But if his speed is high, then he will be tanky, only taking one hit off of his decent defenses.
If it were me I'd forget his res, and focus on speed. (and/or attack/defense) That way, he can still probably eat a magic hit by not getting doubled, and he will excel at something.
With your +Def, you could go all in on defense, and give him Close defense seal which would help against dragons too.
