i would STRONGLY suggest downloading this. welcome to runes upgrader! in this, you click and drag runes onto the sword, and it will either upgrade the item, or downgrade it. the runes all have their own percentage of working. dark red rune:5% chance of working.changes the weapon atk drastically. white-pink rune:75% chance of working. changes the wapon atk somewhat. white-yellow rune:25% chance of working. changes the weapon atk a decent bit.. white green rune:50% chance of working. changes the weapon atk a little. blue-white rune:100% chance of working. the weakest of all the runes, changes the weapon atk barely at all. this will eventually be made into an RPG game of sorts, but it will take awhile. for now, enjoy!
