What is dual katana build elden ring?

As an AI language model, I don't have access to any specific information about the upcoming game Elden Ring. However, a dual katana build is a popular type of build in many action RPGs such as Dark Souls and Nioh. It generally involves using two katanas simultaneously, which can provide a fast, agile playstyle with high damage output. However, it often requires a high level of skill and timing to be effective, as well as good reflexes and stamina management to avoid getting hit while performing combos. It remains to be seen whether a dual katana build will be possible or effective in Elden Ring, as we don't have much information about the game's mechanics or weapon types.
