Problem: On the moment of current post we can’t change slot for rune. If we want so - it is mandatory to purchase/extract from other weapon same rune and put it into desired slot. E.g., I want “Jump Cut” rune being able to use by pressing “SPACE” (runeslot #4 at my case). So I have to find other Wooden Sword with such rune, extrat rune from found weapon, then place it into runeslot #4 in actual used Wooden Sword, instead of just being able swap runeslots on current weapon without timewaste need.
Suggestion: add availability to change rune slot via NPC/inventory menu without need to extract same rune from same weapon. It is very actual when playing on fists weapon because you actively use all 4 runes. Also it may be actual with other weapon which you actively using all rune slots.
