With the recent Patch 1.14 to Elden Ring, a variety of weapon and equipment changes have shaken up the meta once again.

While Greatshields have consistently been strong, they have always come with a massive Equip Load detriment, forcing players to build around them by using fewer or lighter weapons and armor.
