 # Editing a character level
 
-...
+Editing a character's level is a quick way to unlock the flea market and to fill a part of the requirements to get access to higher grade items from the traders.
+
+To do so:
+
+* Open your character profile (`%game%\server\user\%profileId%`) with your code editor.
+* Search for the first line with the `Experience` property.

+
+* Go to the [EFT Wiki Character skills page](https://escapefromtarkov.gamepedia.com/Character_skills#Experience), scroll down to the "Experience" section and copy the `Cumulative Total` value of desired level from the table.
+
+> **Note**\
+> Remember to remove the commas or it will break the file formatting. If you copied `3,873,658` from the table, it should be writtent as `3873658` in the file.
+
+* Replace the experience value from the file with the one copied from the table.
+* Save the file.
+
+On the next server startup the character will be at the desired level.
+
+> **Note**\
+> A character's level, in Escape From Tarkov, is not tied to the `"Level"` property. Instead, it's derived from the amount of experience it has. As such, a character with `781760` experience points will be level 30.
+
+Below is an example with before/after screenshots of the file for a character going from level 1 to level 50.

+
+With this done, your character should now have gained a few levels and you are ready to proceed with the next step, which is [editing the characterskill levels](./#tutorials/tut_0/tut0_3.md).
