Wearing a full set of certain armor gives you permanent effects for as long as you have all four pieces on.
Full Set Effects
You need all four pieces (helmet, chestplate, leggings and boots) of the same set equipped. Take one piece off and the effects stop until you put it back on.
- Full Diamond Set: Speed III, Strength II
- Full Netherite Set: Speed III, Strength II
Damaged armor can be fully repaired at a Repair Station once you reach Prestige 1. See Repair Stations.
