So this multiclass is designed to be fun, not the ultimate anything, but follows the idea of TWF with a dash of undead and Eldritch Knight. It was initially a vampire, but came out a bit of a mess, and a veteran from my guild helped clean it up some, making a few changes, but maintaining the core ideas. It has 9 levels of Ninja Monk, to get the Enhanced Evasion and Wind Stance among other things. It is designed for longsword+shortsword or just two longswords. Offhand extra strike is at 96%, plus plenty of dodge, concealment, and have multiple displacement options to add. That's the core idea. Feedback is welcome.
