there are two ways you could get that
editing the ingame files...
its not complicated but its also NOT RECOMMENDED because messing with ingame files is stupid and can lead to crashes and it not working at all
also its no possible to do that for the browser version
ALSO you would need to re-edit every time the game updates...
i only adding this so you know that it is possible but also that it is also a bad idea
there is however a second safer and simpler way by editing a save file
just save your game on a file open with notepad and change the current equipped weapons on your character
first off: backup your save for obvious reasons
second: equip 2 weapons you wont miss and save the game on a file
third: open that file on notepad and CTRL+F search weaponprimary
look for
\"weaponPrimary\":{\"key\":\"REPLACEWEAPONNAMEHERE\",\"args\":[1]},\"weaponSecondary\":{\"key\":\"REPLACEWEAPONNAMEHERE\",\"args\":[1]}
replace the names of the weapons with Ashelander and Dawnsword be careful to not delete a \ or "
it should look like this
\"weaponPrimary\":{\"key\":\"Ashelander\",\"args\":[1]},\"weaponSecondary\":{\"key\":\"Dawnsword\",\"args\":[1]}
then save the changes and load the file
AGAIN PLEASE create multiple saves if this is the first time you are editing your save by hand, i typed this assuming you never had any experience with this and dont know if i explained well
