"Last on the list of Guardian-grade components is Sapphire Wire, another hard-to-come-by by item formerly favored by Hunters because of its versatility. Sapphire Wire, like Plasteel Plating, was another casualty of the Red War... but you feel confident that you can scrounge some up."
"Gather Sapphire Wire by completing bounties for Ana Bray on Mars, by defeating Hunters in the Crucible, or by completing Escalation Protocol wave. Escalation Protocol waves grant the most efficient progress."
- This final collection mission has you collecting 50 Sapphire Wire.
- You can collect it by completing Bounties for Ana Bray on Mars, completing the Escalation Protocol, and by defeating Hunters in the Crucible.
- Killing Hunters is worth 3 Wire, Bounties are worth 5 Wire, and each Escalation Protocol Wave Clear gives 5 Wire (35 for a Complete 7 wave run).
