xazil,
could you explain what you mean? Thanks.
The Monkeygrip feat, also from the CW, allows you to use a weapon one size larger for -2 penalty to hit.
A powerattack of -2 does +2 damage or +4 damage for twohanded weapons.
It often ends up about the same damge when comparing these two, sometimes a little better sometimes a little worse. Note this is just comparing damage in these cases not taking to account power attacks flexibility and different ACs etc.
The break point tends to be with one handed weapons that do a large amount of damage already. The warmace the most obvious example. Monkeygrip is really a sword and boarders feat, perhaps to give them an edge against twohanders + animated shields.
Monkeygripped large spiked chain is 2d6 = 7 average damage.
Power attacking 2 with a spiked chain is 2d4+4 = 9 average damage.
Monkeygripped large greatsword is 3d6 = 10.5 average damage.
Power attacking 2 with a greatsword is 2d6+4 = 11 average damage.
Monkeygripped large rapier is 1d8 = 4.5 average damage.
Power attacking 2 with a rapier is 1d6+2 = 5.5 average damage.
Monkeygripped large longsword is 2d6 = 7 average damage.
Power attacking 2 with a longsword is 1d8+2 = 6.5 average damage.
Monkeygripped large bastard sword is 2d8 = 9 average damage.
Power attacking 2 with a bastard sword is 1d10+2 = 7.5 average damage.
Monkeygripped large warmace is 3d6 = 10.5 average damage.
Power attacking 2 with a warmace is 1d12+2 = 8.5 average damage.
As a note this gives you an idea how powerful the "powerful build" race feature of goliaths and half-giants actually is.
