Iunno about this one..something around 1m? Just offer.
My old daggers,not perfect and I dont want much for them but i dont wanna let them go to waste so yeah..offer and I'll make you a nice price xD
Just enchanted this one for my TH but got another 17/17 one so yeah..i guess something around 300k~500k would be ok?
13x Guild Coin - 400k each
Fail Witie Gloves - 500k (Upgrade fodder i guess)
Fail Invoke Flame Arrow - 100k (same here)
Also, i always buy good Min/Max Daggers! 80+
