Buy any necklace that is up to level 35 ( + doesn't matter, will pay a little bit extra if it's golden necky and high + ) that has the following bonuses :
1.5k (or 2k) HP
Another optional bonus is 5/10% pierce,will pay extra for it.
6-7 bonuses not neccesarry,but if there's HP in it then it's good.
I am willing to pay a lot of money depending on which bonuses the necklace has. Leave your necky and stats in the comments below and I will reply how much I would be able to pay for it.
