Ethereal is really nice, but it has low attack power and the Vampire suffix kills it, because just as the Illithid and Banshee ones they don't siphon much nor fast enough before you die. Before I could soulfuse my current weapon, an Artic Estoc of Slaughter I used a Fiery Estoc of Balance, and although the increased accuracy from the Balance suffix is nice using the Slaughter one automatically gave me at least 250 extra points of damage, and that does help immensely with survival too so if you had to ask me which one to choose Slaughter is the obvious choice. Check decondelite's auction or shop for 2H weapons, they're on the cheap side and are really strong. Even if you're picky like me about the element there should be options to choose from and something with at least 75% ADB would really boost your damage up.
If you're using leather I personally felt more benefit from Protection ones and in fact only used those but as you get closer to 300 I recommend to start looking for shades, of at least the Magnificent variant. No piercing does suck but Evade is yet another form of defense in the end.
Regarding Rending Blow its advantage comes from spreading the status really fast, so while you might take some damage as soon as you hit with Shatter Strike the damage reduces dramatically the next turn and instead of facing 10 enemies you end up with 5, while the other 5 feed you with overcharge (if they even survived both attacks). Both abilities and Estocs do play nicely as they complement each other and can save you when you're cornered so you can bullshit your way out even though you're clearly outmatched. Note that this might end up being rather slow but as you level up you start using it less and end up being faster as a result.
So first, get a good weapon and hollowforge it. Void damage is just that good and you'll see some nice improvement just by doing it. If you get an elemental one try to match it with the Elemental spikes ability that complements it (fire weapon-elec spikes, ice weapon-fire spikes, etc) for a sliver of extra damage.
There might be a lot to change and maybe some things are more optimal than others but I'm still learning stuff and experimenting too since there don't seem to be many 2H players around to learn from and most of what I know I derived from the DW players, the wiki and old posts all over the place so do forgive me if I ended up giving shaky suggestions but I hope if I said something outrageously wrong the actual experts will correct it :P
I see, didn't expect it to be that bad, although I did notice the health gain was quite small, I'll try going for one with a Slaughter suffix and better ADB then, that does sound a lot more useful for sure. I have been stuck with leather yeah, mostly just switching to whatever new equips I got replacing everything about every 10 levels. I will keep my eyes open for Shades, soul fragments aren't too hard to come by and all this time of just mindlessly playing did give me a decent bit credits to buy a few things. Seems like I also get to figure out how player trading works, seems quite straight forward from the short glance I took so thats good.
Yeah, I really should've had it on the hotbar, I just gave it a try for Longest Journey although only on IWBTH and it's so much easier, might be enough to run up to Eternal Darkness even without fixing my equipment. Thanks for that tip. Speed isn't really a concern for now, it's still not hard to burn the Stamina over the day.
So far the advice seems quite solid, kind of a shame there aren't that many 2H players though, DW actually seems very interesting too but I'm just glad if I can get some progressing done for now and worry about Personas later. Thanks a lot again.
