Heavy Weapons
Heavy weapons, such as those made from gold or platinum, are unwieldy but inflict additional damage. Without the proper Exotic Weapon Proficiency feat (for instance, heavy longsword), you suffer a –4 penalty on attack rolls with a heavy weapon. Only weapons made entirely or largely of metal (such as swords or axes) are affected; other weapons (such as spears) are not. A character can wield a heavy weapon one size category smaller than his own in two hands to avoid the attack penalty. For instance, a human swinging a light mace made of gold with both hands, or an ogre wielding a platinum longsword with two hands, does not suffer the attack penalty.
You can never use the Weapon Finesse feat with a weapon made of a heavy metal. Weapons made of a heavy metal inflict increased damage, as shown in the following table:
| Old Damage (Each Die) | New Damage |
|---|---|
| 1 | 1d2 |
| 1d2 | 1d3 |
| 1d3 | 1d4 |
| 1d6 | 1d8 |
| 1d8 or 1d10 | 2d6 |
| 1d12 | 2d8 |
