If you are hunting Silver Grove Spectres in Warframe, you will need to get your hands on some Frostleaf. You can only find the plant at Corpus Outposts. You can find them on the ground near the edge of cliffs.
You will find Corpus Outpost at the following nodes on the Star Chart:
- Venus – E Gate
- Venus – Linea
- Venus – Unda
- Neptune – Galatea
- Neptune – Sao
- Pluto – Narcissus
- Pluto – Regna
Frostleaf is a small, green plant with a dusting of frost on it, and is very easy to see on the edge of cliff areas. To harvest the plant, you scan it with your Codex or Synthesis Scanners. When collecting this resource, you want to use the Cross-Matrix Widget upgrade you can purchase from Cephalon Simaris for your Synthesis Scanner for 50,000 standing. The widget has a 45 percent chance of counting any successful scan as two scans, yielding twice the resources.
You need Frostleaf to make the Sunrise Apothoic. The locations to find all of the plants you need to make the Sunrise Apothic are listed here:
- Vestan Moss
- Sunlight Jadeleaf
Some of the plants you need for the Apothics will only appear at a specific time. While Frostleaf is not one of those, if you need to check what time of day it is in-game, you can use websites like Deathsnack’s Stuff, or Warframe Hub. These sites are the easiest way to see what time it is on Earth in Warframe, and how long is left in the day/night cycle.
Keep in mind that your Helios Sentinel cannot automatically scan these resources or any other plant resource in the game. You must use your Codex or Synthesis Scanner to harvest them.
