Question: you have a lot of feats you could get whatever weapon you want. What weapon should khelgar use?
Opinion: I think you should either use Dwarven War Axe (comes with it) which is the obvious choice. But this weapon will only crit on 19, 20 with Improved Critical. Another Choice is Scimitar which is less single handed Damage, but a crit on 15-20. Another Choice is longsword for one more damage and crit 17-20. Another Choice is Exotic Bastard or Katana for another 1 damage and same threat range as a longsword. The final choice presuming I want a wide threat range rather than x3 on crits (or its D War Axe) is to take Monkey Grip and use a Great Sword for average damage of 7 vs 3.5 scimitar and 5.5 exotic weapons...the greatsword would also have a 17-20 threat range.
I think the Dwarven Waraxe often overkills and gets much fewer crits. Early access to a +2 Scimitar and thats what I would go for. With his strength and WS it will do a lot of damage and crit like crazy. I would also like to roll through with a Greatsword just for style points
The buildup...some things I take early as possible like blindfighting because khelgar is going to level squat for xp and I hate to fight concealed things with main tank no blindfighting...

20: Taunt 1(23), Heal 1(1); Spring Attack*
Notice I'm using a scimitar...there is a scimitar you can buy that grants whirlwind (which I'm a little short of)..Also scimitar is great on crits threat range. So he can switch to 2 handing his scimitar and do a whirlwind at his highest AB which if you give Bull's Strength and enhance it to +5 he has 20 BAB + 8 STR +5 enhance +2 GWF = 35...which means he will hit AC 37 on a 2...he will crit on 15-20 against AC 50 and he will confirm criticals on a 2 against AC 42... (subtract 3 for power attack)....I do plan on enchanting that scimitar with Vampiric +3 or 5.
After excecuting the whirlwind simply switch back to tower shield
I took Vile Drinker for my main...who doesn't use monkey grip, but tower shields disrupt arcane casting too much and as a bard I CAN use wand of shield.
