    Learning goals

    • Learn when to keep a weapon.
    • Learn when to level a weapon.
    • Learn when selling may be safe.
    • Learn why delaying Foundry claiming can help.
    • Learn why checking crafting requirements matters.

    Explanation

    Weapon slot pressure becomes easier when you use a decision tree. First ask whether the weapon is fully ranked; if not, usually level it before selling. If it is ranked, check whether it is used to craft another weapon. Then check whether it is hard to get again, whether you like using it, and whether buying slots is a practical option. If a weapon is finished in the Foundry but your inventory is full, leaving it unclaimed can reduce pressure while you finish ranking something else.

    What should I do?

    Use this flow: rank it, check crafting use, check reacquisition difficulty, decide if you enjoy it, keep favorites, sell only safe extras, and buy slots when progression feels blocked and you have safe Platinum.

    How to avoid wasting time

    Do not sell weapons blindly based only on tier lists. A weapon can be weak but still useful for Mastery or crafting.

    Common mistakes

    Watch for these beginner inventory and Arsenal mistakes.

    • Selling weapons at rank 12.
    • Selling a weapon needed for another blueprint.
    • Selling rare or annoying-to-reacquire weapons.
    • Claiming Foundry weapons before freeing slots.
    • Buying slots without also managing unused gear.
    • Keeping everything and never ranking new gear.

    Key Takeaways

    • The best weapon slot decision is not sell bad weapons. It is rank, check, then decide.

    Practical task

    This is the main skill for weapon slot management.

    1. Pick three weapons you own.
    2. For each weapon, answer whether it is fully ranked, used for crafting, hard to get again, enjoyable, and something you would miss if sold.
    3. Mark each weapon as Keep, Level first, Check crafting use, Safe sell candidate, or Delay decision.
    4. Do not sell anything until you are confident.

    You can explain the reason behind each keep/sell decision.
