Hi, I have a question. What should I do to get rid of weeds from farm (I've been to the farm with every alliance and none of them helped)?
you need the herbicide
The potion seller (purple wolf in town) will sell it to you after completing all of his quest
If you are too lazy to do their quests you can summon the herbicide to have it in your inventory with a command
>summon Qi_Herbicide_C
To type commands you must press the key to the left of key 1
