Diablo 2 Runewords are the combination of different runes to create an effect that forms "runewords". They work in the following way in Diablo 2 Resurrected. Items used for Diablo 2 Runewords must be gray text items, normal, exceptional, or Elite. Low Quality, Superior, and Ethereal can be used. Magical, Rare, Set, Crafted, or Unique items. Shield runeword bases are often picked based on the strength requirement. Elite light shields or Grim Shield/Troll Nest don't lower the run speed, have a lower strength requirement and have good blocking chance. Paladins should always go for class-specific shields because they can drop with up to +45 to all resistance and higher blocking chance.
