Ways To Get the Sanguine Mutation

In the latest update of Fisch, you can get the Sanguine mutation in a couple of ways. Either use the Sanguine Spire Admin Rod or roll for the Blood Reckoning Enchantment.
Item | Type | Sanguine Mutation Chance | How To Get the Item |
---|---|---|---|
Sanguine Spire | Admin Rod | 30% | Purchase from the Underground Music Venue during the Corruption Event. |
Blood Reckoning | Enchantment | Chance depends on your health | 1/28 chance of getting it by enchanting any rod at the Keepers Altar. |
These are the only ways to get the mutation. Players will not be able to apply Sanguine to their catch by using the Appraisal mechanic, making it quite hard to get.
How To Get Sanguine Spire
You can buy this rod for 10 million in-game currency. However, it only spawns inside the Underground Music Venue during the Corruption Event. This event is Admin Exclusive and does not occur naturally. To get to the location, you first have to complete the Crystal Cove puzzle in the Depths area by placing a Chaotic Enchant Relic on a specific pedestal. Players who are yet to reach this stage of the game are better off using the Blood Reckoning Enchantment to get the Sanguine Mutation.
