Valheim CharData Editor
You can use this tool to load Valheim character data files and edit them. You can modify inventory contents, skill levels, and more.
Simply load your character .fch file (located in C:\Users\[Username]\AppData\LocalLow\IronGate\Valheim\characters
by default), modify the fields you want, and save it. It is highly encouraged to make a backup beforehand.
Notes
hairItem: HairNone, Hair1-4 (braided), Hair5 (long), Hair6-9 (ponytail), Hair10-11 (short), Hair12-14 (sideswept)
beardItem: BeardNone, Beard1-10
modelIndex: must be 0 (male) for beards to work. All setting to 1 does is disable beards. Other values other than 0,1 do nothing
playerData.skinColor: {x: red, y: blue, z: green} where each value is in the range from 0.0 to 1.0. {x: 1.0, y: 0, z: 0} gives you pure red.
playerData.hairColor: same as above
