I just finished a run with a caster heavy group, so I decided to go the other way this time. I've put together a really powerful all physical damage group with a Skald.
GW: Skald - stats not really that important
Jaheira - (main tank with Shield and Club+1 to be replaced with Yeslick once I get him)
Minsc - Dual Wielding Maces & situational use of Spiderbane
Kivan - Using Composite Longbow+1 and dual wielding longswords (Varsicona & The Harrower)
Coran - Using The Dead Shot
For Minsc I put his level 3 pip into Maces and his level 6 one to max out Two Weapon Style.
For Kivan both pips went into Longswords. He's mostly an archer but in some situations dual wields longswords.
Coran is just an archer. I used Imoen up to Beregost just to get The Stupifier then dumped her and went without a thief until I got Coran.
I wasn't planning to replace Jaheira with Yeslick, but I forgot how bad her spell selection is and with Yeslick I'll be able to pump up the damage more with Chant and Skeletons, etc.
I'm going into the Mines now, Haven't entered yet. This group is brutal.
I did use a mod to remove the range on the Bard song because the way the song is implemented in the latest patch it's range is almost useless. Removing the range is a little much, but it was the easiest resolution I could find and I still play as if there is a range. I don't just sit my Bard in a corner of the map or anything.
But basically, Skald song + Haste + Bless + Chant will = massive damage. Not that you really needed it, but if you add in summons it makes it really crazy.
I'm playing on Hard.
