You might imagine sword plus sword is a bit of a redundant pick, but by combining the Sword & Shield with the Greatsword, you can become the ultimate ass-kicking tank. This build allows you to not only mitigate damage exceptionally well with various defensive skills, but you also dish out the hurt using the Greatsword’s hard-hitting abilities. With the right setup, this can also be one of the best farming builds, letting you gather tons of enemies and DPS them down rapidly.
Also consider: A combination of the Sword & Shield + Wand & Tome turns you into a traditional paladin archetype, granting you substantial sustain via healing spells, while offering up some damage-over-time abilities. If raw survivability is your goal, this build is calling your name.
