While this guide will not give exact number for every weapon, it is spot on for 95%+ of the weapons in the PHB and supplements (like Sword and Fist)

All weapons start as Medium d6/20 X2 weapons and get "points" to spend on abilities

- simple weapons get 1 point

- martial weapons get 2 points

- exotic weapons get 3 points

Upping the size category by one increases the die size by one, and decreasing the size category by one decreases the die size by one.

The die sizes are
** d3 <-> d4 <-> d6 <-> d8/2d4/d10 <-> d12/2d6 <-> 2d8**

(as per pg. 162 of the DMG)

You can spend your points in the following ways:

- 1 point per die size increase (max two points spent)
- 1 point per threat range increase (max two points spent)
- 1 point per critical multiplier increase (max two points spent)
- 1 point for reach
- 1 point for ranged weapon (increased range increment is just extra gp cost)
- 2 points for a double-headed weapon
- 2 points to be usable with a monk's UBAB
- 3 points to threaten at both 10' and 5'
- -1 point per weapon size increase
- -1 points to require a move-equivalent action to reload, and reloading draws an AoO
- -3 points to require a standard action or longer to reload, and reloading draws an AoO

So let's try some examples from the PHB:

**Heavy Mace:**medium simple weapon (d6/20 X2, 1 point)

d6 20/X2 + 1 (increase die size) -> d8 20/X2**Light Crossbow**, small simple weapon (d4/20 X2, 1 point)

d4 + 2 (increase die size) + 1 (increase critical range) + 1 (ranged) - 3 (SA to reload, AoO) -> d8/19-20 X2 ranged**Light Pick**, small martial weapon (d4/20 X2, 2 points)

d4 + 2 (increased crit. multiplier) -> d4/20 X4**Scimitar**, medium martial weapon (d6/20 X2, 2 points)

d6 + 2 (increased crit range) -> d6/18-20 X2**Long Sword**, medium martial weapon (d6/20 X2, 2 points)

d6 + 1 (increased dis size) + 1 (increased crit range) -> d8/19-20 X2**Greatsword**, large martial weapon (d8/20 X2, 2 points)

d8 + 1 (increased die size) + 1 (increased crit range) -> 2d6/19-20 X2**Halberd**, large martial weapon (d10/20 X2, 2 points)

d10 + 1 (increased crit mult) + 1 (reach) -> d10/20 X3 (reach)**Longbow**, large martial weapon (d8/20 X2, 2 points)

d8 + 1 (ranged) + 1 (increase crit mult) -> d8/20 X3 (ranged)**Kama, Halfling**, tiny exotic weapon (d3/20 X2, 3 points)

d3 + 1 (increase die size) + 2 (usable with UBAB) -> d4 20/X2 (UBAB)**Hammer, Gnome Hooked**, medium exotic weapon (d6/20 X2, 3 points)

d6 + 2 (double headed) + 1 (crit mult on first head)

+ 2 (crit mult second head) - 1 die size (second head)

-> d6/d4 20/X3 X4**Sword, Two-bladed**, large exotic weapon (d8/20 X2, 3 points)

d8 + 2 (double headed) + 1 (crit range) -> d8/d8, 19-20 X2**Crossbow, Hand**, tiny exotic weapon (d3/20 X2, 3 points)

d3 + 1 (die size) + 1 (ranged) + 1 (crit mult) - 1 (MEA to reload and AoO) -> d4/19-20 X2 (ranged, MEA reload)
