Hero Build Overview/Explanation
Welcome to my meme build!
Kempf has a very simple role: try to hit something and survive if you can. If Kempf manages to trigger the effect of Venin Edge AND survive while doing so, you can pretty much collect your free defense victory.
Usually, you can only accomplish this by using Windsweep/Watersweep when faced with meta threats such as Brave Ike, Brave Hector, or Fallen Edelgard. Even then, you will occasionally have to deal with threats running Null C-Disrupt, particularly Winter Altina. If you aren't capable of building a defense that can suppress Duo Heroes, your next best option may be to go stat-balling on Kempf.
Granted, AR-D Def/Res is nothing if not incredibly rare. You can only get it from Kjelle (who's that again?). You could potentially run Fortess Def/Res as well, but I shouldn't understate the importance of "stat-balling." You MUST make Kempf as hard to kill as possible, especially if you want to use Lunge. If you cannot manage this, your opponent will just use Ninja Lyn to ruin your fun.
By using Lunge, you can pull of some particularly evil stunts. If your Kempf is as tough as can be, chances are Kempf will manage to survive all but the most one-sided of encounters. Even in a handful of cases, Kempf may come out clinging to life, but this is where the fun starts: your Kempf has not only crippled the enemy's ability to counterattack, but Kempf himself can now act as a "Wings of Mercy beacon." In other words, by building your Aether Raids defense properly, you can potentially make Kempf act as a red herring when your opponent is faced with your team's actual threats.
Consider something like Lysithea. As long as you make Lysithea as hard to reach as possible, your opponent will be forced to do SOMETHING about Kempf before they are able to get to Lysithea. If they do not have the proper core options, they may be forced to engage Kempf at a disadvantage and pray they can weather the assault of all of the other units on your defense team.
Just remember one important thing. Kempf cannot succeed in a vacuum. You must have OTHER hard hitting units to make up for Kempf's average combat ability. Venin Edge is not strictly a weapon that lets you win; it is a weapon that lets you win harder.
