As we can see in some NPC of Haven, it seems to be possible to add this option to the game for every knight. Maybe its harder with bigger swords, bombs or guns.
Bombs and guns(maybe with a little size adjustment) could be placed at the knight's waist.
Normal swords could be placed diagonally at the knight's back.
Big swords could be placed vertically at the knight's back.
Swords would be behind the shields.
-There is space
-The work for swords is half done
-It would be motivating and cool
-OOO, pls
few months ago someone suggested the same thing but elaborated! more! on it.
I like thier suggestion more than yours.
You have to pay it as a cosmetic to have it strapped to your back.
+1 as a usable of some sort.
