Crimson Desert: How to Upgrade Stamina Past Level 10 and Find Red Seaweed

If your Stamina skill in Crimson Desert is stuck at Level 10, you are not alone. Many players reach this point and wonder why they can no longer upgrade the stat. The reason is that further upgrades require a special material called Red Seaweed, along with a knowledge unlock tied to research progression. This guide explains where to find Red Seaweed and how to unlock the knowledge required to continue increasing your stamina to the maximum level in Crimson Desert.


Why Stamina Stops at Level 10

Once your stamina reaches Level 10, normal upgrades stop. To progress further, the game requires below mentioned items.

  • 10 Red Seaweed
  • The Power of Life knowledge upgrade

Where to Find Red Seaweed

Red Seaweed is mainly found along the southern coastline of the map. It blends into the environment, so it can be easy to miss if you are not looking carefully. Look for small red seaweed clusters resting on rocks or in the sand near the shoreline.

Travel to the southern coast and search near the shoreline rocks. One cluster here gives around 5 Red Seaweed. Below maps shows a few areas where you can find the Red Seaweed.


How to Unlock the Power of Life Knowledge

Travel to the Urdavah region in the top-right part of the Crimson Desert map. Inside the large walled city, locate the Research Institute. Speak to the researcher there and complete his initial request. This unlocks the research tree.


Research Tree Requirement

Once the research system opens, begin progressing through the upgrades until you reach the Red Seaweed research node. Unlocking this node grants the Power of Life knowledge required for further stamina upgrades.


Upgrade Stamina Beyond Level 10

After collecting 10 Red Seaweed and unlocking the Power of Life knowledge, return to your skill menu. You will then be able to continue upgrading your stamina beyond Level 10 and eventually raise it to the maximum level.
