Completing an Incursion permanently unlocks its associated weapon for purchase from the Wayfarer.

WHERE & HOW TO FARM
Where to farm
The Incursion map associated with the weapon you want, followed by the Wayfarer in Town.
Incursion weapons are attached to special maps and their encounter rules. Completing the relevant Incursion permanently unlocks its weapon at the Wayfarer, where it costs Defender Medals. The victory chest on that same map can also offer the weapon, but that chance is separate from the guaranteed purchase unlock. Identify the map tied to your target before farming.
Unlock the relevant Incursion through Chaos Expedition progression.
Have a build suited to the Incursion’s altered encounter and mutators.
Save 500 Defender Medals for the Wayfarer purchase if you want the guaranteed weapon.
Open Incursions and identify the map associated with the target weapon.
Read the special encounter rules and enemy schedule before beginning.
Build defenses to counter the map’s unique challenge and any listed mutators.
Complete the Incursion’s waves and victory condition.
Claim the completion reward; this permanently unlocks the map’s weapon at the Wayfarer.
Visit the Wayfarer and purchase the weapon for 500 Defender Medals if you want a direct copy.
Replay the map only if you want another victory-chest chance or further completion rewards.
Farming tips
The map completion unlock is permanent, so you do not need to replay solely to unlock the purchase again.
Many Incursion weapons can also appear in that map’s victory chest, but the chest chance is not guaranteed.
Repeat, collect and use
The purchase unlock is one-time and permanent for the account; the Wayfarer purchase costs medals per weapon. Replays provide further chest chances, not a guaranteed duplicate.
Common mistakes
Repeating the Incursion before checking the Wayfarer unlock; buy the weapon directly once unlocked if that is your goal.
Assuming the victory chest always gives the weapon; use the guaranteed medal purchase for certainty.
When to stop or switch
Stop after obtaining the weapon or when you have enough medals and no longer need chest chances; switch to another Incursion for a different weapon.
