Expanded Weapon Size Damage (3.5e Variant Rule)

Sometimes you need weapon damages above Colossal size, but it's difficult to find information on it as it has never officially been codified. Fortunately there is a weapon damage progression that can be extrapolated. Here it is.

Expanded Weapon Size Damage
Weapons either follow the typical d6 progression, or the d8 progression for weapons that deal 1d10 damage as medium weapons (such as bastard swords or heavy crossbow). This chart starts from the last recorded damage (colossal) and goes from there. The sizes below are the Immortal Handbook sizes, they are equal to using Colossal+, Colossal++, Colossal+++, and so forth. The examples use Longsword and Bastard Sword examples, other weapons generally follow the Longsword chart as appropriate. Dice averages have been placed in parenthesis.

Variant Expanded Weapon Size Damage
The doubling can be troubling if you are for some reason fighting something really really big, or your player has somehow become ginormous themselves. Here is a variant progression which multiplies slower.
