While the Builder isn't a combat specialist, having good equipment is still important for survival. Prioritize armor that offers high defense, as you'll often be in the thick of things, even if Malroth is doing most of the fighting. Weapons for the Builder generally focus on utility or area-of-effect rather than raw damage. For example, the War Hammer is excellent for breaking multiple blocks at once, while the Sword of Ruin (a late-game weapon) offers good damage. Don't forget accessories like the Ring of Immunity (prevents status effects) or the Gale Gauntlets (increases attack speed). Always craft the best available gear as you unlock new recipes, especially before tackling boss battles or challenging areas. Remember, your tools are often more important than your weapons.
