how to get deep iron skull and bones

Deep Iron in Skull and Bones is mainly obtained through limited weekly shop purchases and high‑level endgame activities that reward it as a rare material. It is primarily used to upgrade the Frigate, so plan around weekly caps and group content if you want a steady flow.

What Deep Iron Is For

• Deep Iron is a rare upgrade material used for late‑game ship upgrades, especially the Frigate, one of the strongest ships in the game.

• Because Frigate upgrades require a lot of Deep Iron, players often route their weekly activities around farming it efficiently.

Main Ways To Get Deep Iron

• Buy Deep Iron from Blackwood in Sainte‑Anne via the buy/sell menu, paying with Guild Marks and limited to a small amount per weekly reset.

• Purchase additional Deep Iron from another seasonal/weekly vendor (e.g., Tlock/seasonal shop) so that, combined, you can get roughly double the weekly amount before the next reset.

• Join high‑level co‑op content such as Megaforts or tough late‑game activities, which are tuned for groups and drop Deep Iron as high‑tier rewards.

Extra Community Tips

• Some players recommend targeting specific high‑level activities like Wolvenhol and similar endgame encounters, then pairing that with your weekly Blackwood purchases for the best balance of time vs. rewards.

• Forum discussions also describe Deep Iron coming from dangerous areas like enemy strongholds or deep cave‑like zones, so going with a group and proper gear makes farming safer and more consistent.

Weekly Planning Advice

• Always cap your weekly vendor purchases first so you do not miss easy guaranteed Deep Iron.

• Then use any remaining time to farm challenging group content that drops Deep Iron, since this is effectively your “uncapped” source as long as you can reliably clear it.

TL;DR: To “get Deep Iron Skull and Bones,” hit your weekly vendor limits (Blackwood and any seasonal vendor) every reset, then focus on Megaforts/Wolvenhol‑style group content to stockpile enough for all your Frigate upgrades.
