Complete 12 Interceptor Gear I Challenges.

The Interceptor is one of the four javelin types in the game. You will unlock javelins at Levels 2, 8, 16, and 28.

Javelin challenges task you with completing four missions or world events with a specific item equipped. You can equip up to three items from the list below at the same time, though only two go in the support slot, meaning you need a minimum of 20 missions to do four missions with each item. You do not begin the game with one of each type, so be sure to complete some events to get chests and return to the Fort to get the loot after completing a few challenges, then swap for new items and head back out.

For the Interceptor, complete challenges for the following items: Target Beacon, Spark Dash, Wraith Strike, Plasma Star, Venom Bomb, Cluster Mine, Cryo Glaive, Detonating Strike, Rally Cry, Searching Glaive, Tempest Strike, and Venom Spray.
