Minsc can weild 2 weapons. But with the best 3-star Two Weapon Style, each of the weapon will suffer -2 penalty also. Do you think it is worth? Or put the prof at others like Two Handed Sword Style?

How does the 2 weapons damage work?

I dont think that's right, with 3* in two-weapon style you get no penalty on main-hand weapon and -2 penalty on off-hand weapon.

Damage should work normally - full on each weapon, at the expense of using a shield, though I am not absolutely sure. Damage might be calculated like in 3E, half strenght bonus on each hand, but tis unlikely.

Main Hand gets multiple attacks
Off Hand is always set at one attack/round (exceptions are weapons that increase number of attacks like "Belm").

With three stars (recommended, don't settle with two stars or less) in Two Weapon Style only the Off Hand gest a penalty of 2 to THAC0.

IMHO Two Weapon Style is generally not a good idea. Fighters, Rangers and Paladins are generally better off either using a shield or picking Single Weapon Style.

You should compare the abilities of the shield with the abilities of the weapon you intend to use in your Off Hand.

It seems, as if this weapon style was implemented for players that like to dualwield From Faeyr (off hand) and C'Fury (main hand) ;) :D :p
I never use it I´m completely happy with single weapon style.

Mee to, Ragusa. Mee too.

Exactly Ragusa!
You stick that Girdle of... oops, that isn't a girdle, it's Crom Faeyr.

Rangers are great with 2 weapons. WHen playing with Minsc I would say go for 2 weapon style. It realy is worth it. Minsc with 2 weapons is a real tank, you can always use a fighter with shield-long sword with very low AC to get the first kicks....

So off-hand weapon generally adds 1 attack per round to your total, but with -2 to hit penalty at best. Well, still not bad, especially for some people who shun (likes of me) or cannot use (kensai, swashbuckler) shields and are better off with dealing massive damage quick than defending themselves with additional -2 AC bonus from Single Weapon style specialization.

indeed, off course the off-hand isn't that good as the main hand but the penalty isn't that bad and remember, when you have a weaopon with a abilty in the off hand, like Crom Faeyr witch sets str to 25 it''s also for the main hand
