You can purchase Basic Tech Upgrades from vendors on Earth Spacedock and Qo’noS, but you’ll need to craft Improved or Superior Tech Upgrades, or purchase them from the exchange or from a friend with a high level of R&D skill.
Each Tech Upgrade works on a specific type of items. Tech Upgrades will initially come in three grades – Basic, Improved, and Superior. To upgrade your gear, you’ll apply new Tech Upgrade items. The Upgrade system will let you take those Breen shields, caustic plasma beams, and old Mark 10 MACO armor and improve them to Mark 12 – and beyond! Fleet gear upgrades work the same way! The gear will keep its current mods, go up in mark, and can potentially become epic (gold) quality gear. If you have a favorite weapon from a mission, but it’s not up to the quality that you need, or if you have an old version of gear that isn’t up to the best Mark that your character can use, you can now make that gear better. With the Upgrade system, you can take any gear that has a Mark and improve it. Your captain will now be able to use Mark 13 and 14 gear, and the best part is, you’ll be able to do this by upgrading your existing gear to make it better. As part of the new level increase in Delta Rising, we’re bringing up the Mark of the gear available in Star Trek Online.
