Pros and Cons
The biggest benefit of two weapon combat is the extra swing that the character gets. There are a few things that are different when a weapon is swung in the off-hand, such as roundtime, attack strength (AS), and defensive strength (DS).
Roundtime
Roundtime is calculated based on the base roundtime of each weapon, the weight of the off-hand weapon, and the user's strength. Swinging two weapons at once is far faster than swinging each of the weapons individually, but only fast off-hand weapons add no penalty whatsoever to swing speed. For the lowest roundtime, the weapon in the off hand should be at least as fast as the weapon in the right hand and should not be very heavy. To use an off-hand weapon without penalty, you must have the following strength bonuses:
| Off-hand Weight | Minimum Strength Bonus |
|---|---|
| 3 pounds | +5 |
| 4 pounds | +20 |
| 5 pounds | +35 |
- See the Melee Roundtime article for an in-depth discussion of the factors that go into the calculation.
Attack Strength
The AS of a swing takes into account the character's skill with the weapon itself, and their skill in TWC. 3/5ths of one's skill in the weapon type accounts for the character's AS, while 2/5ths are the character's training in TWC itself. Also, if a character's strength bonus is higher than the character's dexterity bonus, the off-hand attack will be limited by the character's dexterity. More often than not, this comes into play when a character uses the combat maneuver, Surge of Strength.
Additionally, a character that trains in TWC twice per level has no chance of "not finding an opening for the off-hand strike" when swinging at a target up to five levels higher than themselves. Less training reduces the chances of the off-hand strike from occurring. Training in TWC 1.5 times per level reduces the level of the guaranteed strike to like-level with the swinger, and training only once per level reduces the chances to 80% when swinging at a target that is the same level as the swinger.
Defensive Strength
A character's DS when using an off-hand weapon is calculated similarly to the DS granted from their primary weapon training. While the primary weapon grants DS according to the following formula
Off-hand weapon DS is calculated by the following formula:
Where stance is 0.00 (in OFF), 0.20 (ADV), 0.40 (FOR), 0.60 (NEU), 0.80 (GUA), 1.00 (DEF), and STR and DEX refers to the bonuses given to the Strength stat and Dexterity stat. The +5 at the end of the formula is +15 instead if the user is wielding either a main gauche or a sai in the off-hand.
A character's DS with an open off hand is calculated slightly differently:
Stance modifiers for empty off hand are 0.10 (in OFF), 0.15 (ADV), 0.20 (FOR), 0.25 (NEU), 0.30 (GUA), 0.35 (DEF). The +5/+15 at the end of the formula depends on your TWC training; a character with at least 0.5x TWC per level receives the +15 modifier.
