+@Description("""
+	           The skull texture of a player head.
+	           Allows you to give a skull a custom texture (e.g. instead of it being a Steve head, it's Notch's head).
+	           For the %string% you input a base64 string (think of it like the ID/texture so Minecraft knows what the head should look like).
+	           (The most common place to get a base64 string is https://minecraft-heads.com)
+	           Resetting the texture of a skull will make it look like a Steve/Alex head.
