I recently hit 52 on my BD sub. I have a +6 doom heavy set, +7 tsu*sls, and lv 60 se buffs most of the time. I am grinding in apostate or EV atm. Could anyone with some Bd experience reccomend a better place from 52-61. Another question is, at what level does the BD start requiring partys to get good xp. I can solo incredible easy with my SE as long as I bring a TON of ss. I imagine this cant last for to much longer.

Oh! That Majestic heavy looks sexy on my human BD. I wonder if its worth getting instead of tallum :D

You can find parties as soon as you become BD really... lucky... SwS can't find parties until 49 >.< Once you have the nuker buff dance, go find a SH in decent gear and xpxpxpxp.
I would recommend majestic heavy instead of tallum heavy. The stun resist goes a long way and the p.atk bonus isn't too bad either. Tallum heavy gives attack speed, but that's about it. Try to get OE tallum*damascus for A grade after. Kinda hard to find and expensive when you do, but better than kesh*kesh and it's pretty good. The +7 tsu*sls is pretty good too with the crit bonus and with the crit damage dance. I guess you could keep that a little longer too. If you can OE it even more, keep it for sure.

Well now I have augmented +16 TSU*SLS. It has red flames going down the side. Its probably the coolest weapon I have ever seen. I know I can find parties. What I'm saying is I can also solo really easily for good xp. At what level will I NEED parties to level.

your wish to party will probably increase from lvl 60 onwards. its not like you absolutely need to party but it will be much better going than solo. with an SE at your side you will be able to solo up to 75 if you wish so. there are surprising many spots that will give you good xp solo/duo and with good equpiment like yours it will be no big deal.

but like Silent said, why would any BD want to go solo when they can get into archer or mage parties for insanely fast, easy and cheap xp.

I agree! I had a 52 SH sub and I switched to BD just because I want to party and help people :D

+16 augmented tsu*sls? You lucky son of a ... I wish I had a +16 kris.
