As a new comer with no mesos or nx, is it possible for me to hp wash at lvl 200? or will i have to waste time doing 1 char, funding for hp wash so then i can only make another char with hp wash?
While it is possible to HP wash at level 200 (since you can use AP resets anytime you want provided you have the AP for it), we're a low rate server and it really isn't that easy to get to 200. But I washed some HP unfunded on my NL, with something like 25 base int as well as some INT equipment I got along the way, and I was able to survive Zak without HB by Level 70 or so. You absolutely do not need to be funded to HP wash, but it helps.
Even though the rates are considered low, they are still very very easy to get by on, on top of the daily free NX. So yes it is very possible. Check out this thread if you haven't. http://royals.ms/forum/showthread.php?t=8286
There was a similar question asked by another 'new' player here, it was posted almost a month ago so it's still pretty useful at that.
