gratz on the find.
I guess this is second known unlimited X Lacerating chip out there.
I bought the first one for TT+3800, some players not long after the sale, "suggested" they would pay 7k+
Saying you would and actually paying are two different things. But people did say I bought it cheap, personally I felt at the time it wasn't worth more than 3K, but paid more to secure it.
I can kill spiders and prots with it. CP is easy, even in the caves with this chip. Add T2 enhancers and it does pack quite a punch. It's better than a corrosive chip, more powerful and more range.
The plus side with the chip is it skills Cyogenics and that is a pretty popular MF Profession. Your challenge will be the number of players with the skills to use it, that want to buy it. That in truth will dictate the price.
I guess it's worth anywhere between 2K - 6K, massive swing, however like anything in EU these days appetite to invest is falling. So good luck finding a buyer.
Nice chip
