[3.13] Varunastra Dual Strike Berserker

Just a heads up if you want to improve the build through simple mathematics: Fettle is never worth it if you have access to unallocated 5% life notes in your tree. Replace the small cluster jewels with regular ones with %life and crit multi, and spend the remaining points on 5% life notes. Even 10c jewels are more than good enough for it to be a big improvement.
