Legendary Ship Mods
Legendary Ship Mods adds craftable legendary ship equipment modifications to X4. These modifications use a new Legendary quality tier in the ship modification workbench and are unlocked through Boso Ta research after the vanilla MK3 modification research has been completed.
Disclaimer
These legendary mods are very rare, but also very strong.
