I put my first 10 pts into vita then rest into str.
I got into a part and went from lvl5-71 in about an hour and a half.
got some gear of marketplace feel free to look..

I dont know if i am ready for MQ..
Any suggestions, anything i should buy before i go?
do i do it solo or in a grp?

anything you would like to add?

Do it solo, but not for difficulty reasons. There is a "bug" in the game where if people in the group abandon it / kick you while you are attempting, you can fail. (at least there was, I havn't experienced it lately because I always do it solo since I had it fail on me once)

It's more of a matter of luck than difficulty, you won't need fancy items or need to buy anything special. You could do it naked if you wanted, and I highly recommend it sometime, very uplifting and carefree feeling.

If you are level 71+, you are ready. Good luck!

just one important thing:
be in a guild before you do the master quest.
some guilds are even paying for guild points.. like hbd or master gamers

then just do the master quest. no worries. it is all about luck
