QUOTE=szilard]Another way of handling it, if you want to go in a different direction:
With an exotic weapon proficiency, the long halberd can be wielded either as a normal halberd or as a halberd with 10' reach, but doing 1d8 damage.
- Stuart[/QUOTE]Awful ungenerous unless you are trying to balance out the weapon’s synergy with enlarge person. 1d10 is just an awful die until you leave medium size behind. Once that happens you begin to reap the rewards of wotc being unwilling to include a “1d6 & 1d8” weapon damage step between 2d6 and 2d8.
I think a Long Halberd [+ reach] and a hefty halberd [Medium damage = 2d6] would be ok weapons.
As it happens, these is something odd in the weapon design set up. While wotc made a bastard [1d10 x3 crit, 1 hand exotic-2 handed martial] hammer called the maul, there is no "great hammer" [2d6 or 1d12 x3 crit 2-handed martial]. The titan has a special ability to obtain his version of that weapon, but for a PC to get a full sized 2 handed hammer, they have to grab a large warhammer and suck up a -2 to hit for it being a large creature's one handed weapon.
To complicate things the MM4 has introduced an exotic Medium 2-hand 2d6 x4 crit weapon [erroneously listed with a 19-20 crit in addition to the x4, I say erroneous because the weapon in the monster listing does not have the extended crit. Wotc promised us NO extended and multiplied crit weapons IIRC.]
