For the Guardian Weapon Blueprint, go to col 173 sector OD-J B25-2 planet B 1.
I made a video about this.
Make an explorer kitted ship.
A Diamondback Explorer will do.
I did it in a slightly engineered AspX.
This is a 1.000Ly plus journey, so the more jumprange you have, the more you’ll enjoy the experience.
Land your ship west of point 5.
Remember to have a top-mounted Point Defense unit. This will take care of most Missiles from Sentinels.
Find “Guardian Relic”. These can be shot down from pillars scattered about the place.
The Energy Pylons will come up from the ground after you visit position 1.
Shoot the Pylons in whatever order suits you, and get back to position 1 before the timer runs out.
Eject the Relic at the lighted area in front of the main structure and scan the big Orb that comes up from the main structure.
When you are attacked by Sentinels, keep PIPs on SYS until they discharge torpedoes. They can only fire one weapon at a time.
They will not engage unless you are closer than 190 meters from the Sentinel, even when fired upon.
But some will spawn near your location, and it is very helpful to engage the hand break when they do.
Their missiles will turn your SRV on it’s head.
This can all be repeated as many times as needed, just log in again and start over.
Be sure to repair, and rearm your SRV if you go at them again.
To run out of ammo between four Sentinels WILL send you directly to your ship, and your SRV will be lost.
