आप should do the quest Cold Comfort Farmer before going to the Spire. Once आप return आप should do the quest Blind Date. After finishing Blind Date, buy the farm house and हटाइए in. Remove the key to the cellar from the closet on the सेकंड floor and then rent the property out. The weapon will not appear if आप are living there. अगला go into the cellar that आप find in the खलिहान of the farm. Your dog will lead आप to the Dig Spot where आप will find the Enforcer rifle.
