Gear crafting starts with the Crafting NPC in the Upgrades area. The NPC shows the gear list, required materials, and Gold cost. The craft makes sense after the wearer is clear: carry, boss damage, tank, support, or farm/economy.
Pick the target unit before farming materials. If your main damage unit is failing to kill bosses, gear that raises damage pressure is the first serious target. If waves are leaking while a tank is supposed to hold pressure, defensive or survival value matters more. If the team needs economy, spend materials on a unit that actually changes placement timing.
Read the recipe before picking the farming act. Different material tiers are tied to different worlds and act ranges, including early Leaf Village acts for basic materials, GT City for higher tiers, and Marine Lobby for later materials. Replaying an easy act works for low-tier gear only when that act drops the material named by the Crafting NPC.
Use rarity as a progression ladder. Rare and Epic gear can stabilize a new account when the material cost is low and the unit will stay relevant for several stages. Legendary, Mythic, and Secret gear are better targets after the roster is stable and the account can farm later acts. Early gear is fine when it clears a stage wall; later recipes fit permanent units.
Gold matters as much as materials. If a recipe consumes Gold that you also need for perks, choose the upgrade that changes clears faster. A perk upgrade can affect every run, while gear improves one unit or role. Craft when the unit is important enough that the gear beats the next perk upgrade. If placement money is the loss, Max Yen or Yen Generation may come first.
Watch set bonuses, then finish full sets after the unit earns them. One gear piece is enough when it fixes a real problem. Finish a set when the unit is already core to the team and the remaining pieces come from content you can farm reliably.
After crafting, test the gear in the stage that made you craft it. If a boss survived too long, see whether the damage unit now reaches the kill window. If leaks were the issue, see whether the defensive unit holds long enough for damage to catch up. If the gear does not change the loss, inspect traits, perks, or team composition before crafting more of the same type.
Before a long material farm, check the Crafting NPC again. Costs, material names, and gear values can change after updates, and the NPC screen gives the final material target for the version you are playing.
