which set should i get?

[Nutsuka]

If you got full sets don't change parts for it before you get full set. just looking that chest piece.

If you got high lvl friends ask them bring you to Lynch nightmare, most of us can run it alone already, if your server new then you go moon nightmare or dt nm teams. but S71 is so old there sure are high lvl players already if most of them aren't quited ones. and throw those green treasure maps away you can pick every day 5 when you need those

[DemonRockstar]

ummm wth have you been doing all this time?

Also why would someone with so little inventory space use up over 1/6 of that space with green treasure maps :/

Pick up the 55 set from arena shop asap, and then start running nm den/DT until you can make the 60 set. Your BR is too low for nm Lych at the moment.

this is my current note i have no crystal loids

Generally it's a good idea to have the highest set for your level,which would be the level 70 set.
If there are people on your server or guild willing to help you get that,considering your BR,then that would be the one to go for.
If you can't find such a thing,just get a lower one until you can handle running LL without having to ask for help.

Also,if it was me,I would change that chestpiece first.
