1. Come outta the Northern Outpost. Stand perpenticular to the closed doors.
2. Turn 1/2 right and you will see a ridge line pointing between 2 slanting trees that are pointing to the right.
3. Follow this ridge line and you will see an empty pond on right, pond with a fallen tree in the water on left, continue down the ridge line
4. Now one of those pointing trees are in front of you, with 2 rocks on your left, and a larger pond in front of you.
5. A static spawn Crawler is by that tree, a static spawn Crawler is in the frontal pond, and a static Crawler is approximately at 1 o'clock over that pond.
6. I have seen the Luminii Crawler spawn in the place of the Static Crawler in the pond, and at the place of the Crawler at 1 o'clock.
7. /locs are:
Pond Crawler -> +1340,-297, +166
1 o'clock Crawler -> +1422, -461, +178
*Notes: If you cannot see far out enough to see the 2 trees pointing to the right, the beginning of the ridge line is +970, -80, 193
