As the name implies, they are crimson in color, contrasting their green cousin, the Nirnroot. More than thirty samples can be collected from within Blackreach, including those found in the abandoned laboratory of renowned alchemist, Sinderion. Outside of Blackreach, samples are far less abundant. After reading the journal found in Sinderion's Field Laboratory, or finding one of the Crimson Nirnroot, the quest, "A Return To Your Roots" begins. The quest mirrors The Elder Scrolls IV: Oblivion quest, "Seeking Your Roots". Crimson Nirnroots glow and emanate a unique sound.
Biology
Glow and chime
Nirnroot is distinguished from other plants due to their aural glow and the chiming sounds heard when in close proximity to a patch. Crimson Nirnroot also possess this property, although the chiming sound emitted from them is slightly off-key. The Crimson Nirnroot saplings that grow back, while unable to be harvested, do emit a small glow.
Growth
According to the last paragraph of Sinderion's Field Journal, Crimson Nirnroot is attracted to water just like Nirnroot is. The Crimson Nirnroot often grows near fungi in Blackreach, which sustains the Nirnroot and allows it to grow away from an open water source. Crimson Nirnroot also regrows, unlike its common counterpart.
Locations
In Blackreach, there are at least 44 Known locations where Crimson Nirnroot grow, including Sinderion's Field Laboratory, Silent Ruin and the Derelict Pumphouse. They respawn after 10 in-game days, and are not affected by the Alchemy perk Green Thumb, as they only have one root.
Although sightings of Crimson Nirnroot outside of Blackreach have been reported, they remain unconfirmed.
Quests
- A Return To Your Roots: Bring 30 of them to Avrusa Sarethi
- Ingun Black-Briar's miscellaneous quest: Ingun requests 20 Nirnroots, but she will accept Crimson Nirnroots as well.
Potions
- Main article: Potions (Skyrim)
When mixed with ordinary Nirnroot, the Crimson variant creates a potion with four effects, since both roots have all their properties in common; however, this precludes any further effects from being added.
