Hero Build Overview/Explanation
This is an extremely basic dodge tank build, but I'd argue Sealed Falchion turns Lucina/Masked Marth into one of the best and most reliable of them all. +10 atk/spd/def and +5 res allows her to dish out tons of damage, reliably secure Repel's 40% reduction, double all but the fastest units, and Tank fairly reliably. The icing on the cake is the follow up negation, which acts as a pseudo-null follow up in many cases, improving her matchup against units like Bramimond or V!Lif, however unlike Mareeta or Ryoma, this skill will not negate Impact Skills or wary fighter, so it only increases her defensive potential rather than offensive like Null Follow Up would. The rest of her kit is basic, it simply grants more spd and res, her most important stat and her stat that Sealed Falchion doesn't buff as high respectively.
