First, thanks to Spartankiller13 for helping brainstorm this build idea in the Request a Build, Get a Build thread. The idea being that I was looking to finish up some melee lives on a primarily caster character. For barbarian that turns out to be a 13 barbarian/7 bard split. Here are some notes on my experiences.
To being with, everyone is playing Hardcore, including me. So, when I do need a break from the ramped-up tension of HC and I'm not raiding I pop over to this character. Invariably, this means progress is slow, both because I'm not playing them a lot and since most people seem to be following a similar pattern (or playing HC exclusively) there are few LFMs on my main (Orien) server so I'm either soloing or duoing reaper (1).
I ended up picking Tiefling as my race. Any race can do this. I chose Tiefling because I think they look cool and you get a charisma boost. Starting stats are STR 17, DEX 10, CON 17, INT 10, WIS 8, CHA 16. My first six levels have been barbarian and while I'm taking the SWF feats (1 - SWF, 3 - precision, 6 - ISWF) I've been THF with the Ethereal greatsword and Carnifex. I have Elyd's Edge upgraded, but it didn't do as much damage as Carnifex on L5. Going to see now at L6 if it starts to pull even with ISWF. It's also possible I'll use Yarkuch's Greatsword at L6. Something of a bummer that Sword of the Thirty is btc and I can't swap it over from my Paladin. I've accepted my DPS will be substandard until I get to 10 when I pick up the Forgotten Ax which this build is based around.
Since I haven't played a barbarian in a long time, the thing which most impresses me is the run speed. It's, well, glorious. You are so fast! Sprint boost can zoom you through traps before they trigger. That's fun. As I said, DPS isn't optimal since I'm THF now while taking SWF feats but it's been strong enough where I haven't run into any trouble except in Heart of the Problem (which I feel is the most difficult low-level quest on reaper). I was grouping with another player and a hireling and all three of us died in the final room. And that was after me double Blood Tributing. I had to Jibbers and BT again to finish the quest. Everything else has gone smoothly and I'm at 208 HPs at L6. Blood Tribute allows you to power through almost any situation, but you already know that.
Planned enhancements are 32 points in Frenzy Berserker (for Focused Wrath), 14 in Swashbuckler (for stance), 10 Spellsinger, 11 Feydark leaving 13 points left. Although, realistically, since this is only for a PL and I won't see the points for 19 or 20 I only have 5 points left.
I'm not banking any xp since I want to get to 10 as fast as possible for my ax. I don't expect much trouble at level 6 (quests are still easy) or level 7 (3BC makes it fly by) but 8 and 9 are going to be where I feel push back if I'm still using a Carnifex/Yarkuck's combo without THF feats. Might dig around on an alt for a better SWF weapon.
