As the title says, need to unbind one 155 weapon. Or 155/160 equipments cant be unbinded yet?
I shall guess that you meant (in your question above) to ask if it costs more to unbind a level 155 item than a level 150 item.
Currently IGG only sells 3 kinds of unbinding tools
level 120 Basic Unbinding Tool - 60 points (regular price) / 40 points (when in Hot Sale)
level 140 Advanced Unbinding Tool - 400 points (regular price) / 200 points (when in Hot Sale)
level 150 Expert Unbinding Tool - 2,500 points (regular price) / 1220 points (when in Hot Sale)
please view the item mall: http://vc.igg.com/mall/item_search.php?key=unbind&x=47&y=13
the problem with the description on the level 150 tool is the words "150 or below"
(140 is "140 or below"... 120 is "120 or below" )
but since IGG has not introduced a level 160 tool yet... I guess they have to honor the 150 tool.
keep your fingers crossed they do not invent one.
and please do not leave any ideas of how they could charge more.
