How to Craft Champion Petra, Dragonsbane, and Shield of Infinity Sets
Champion Petra
Champion Petra armor is a four-piece set: Champion Petra Helmet, Champion Petra Chestplate, Champion Petra Leggings, and Champion Petra Boots. Craft each piece with its shaped recipe, then equip all four in the armor slots. This is separate from the standard Petra's Helmet, Petra's Chestplate, Petra's Leggings, and Petra's Boots, which are their own set.
Dragonsbane
Dragonsbane follows the same structure: Dragonsbane Helmet, Dragonsbane Chestplate, Dragonsbane Leggings, and Dragonsbane Boots. Craft each slot individually at a crafting table and equip the full set for the complete look.
Shield of Infinity
Shield of Infinity is also a four-piece set: Shield of Infinity Helmet, Shield of Infinity Chestplate, Shield of Infinity Leggings, and Shield of Infinity Boots. Craft and equip them the same way as the other sets.
Mixing pieces across sets
All of these pieces use standard armor slots, so you can combine them. For example, wear Champion Petra Helmet with Dragonsbane Chestplate, Shield of Infinity Leggings, and Dragonsbane Boots. Check each piece's tooltip before crafting so you spend materials on the slots that give you the protection or appearance you actually want.
