I'm currently in a Terrinoth game playing a sword-and-board fighter. I'm thinking of how best to capitalize on the fact that he uses a sword and shield. From what I can gather from various talents, weapon attachments, and shields available, it looks like my best bet is to put the Balanced Hilt attachment on the shield to get rid of its Inaccurate quality. Then I pick up both the Dual Wielder and Shield Slam talents, meaning my character can then two-weapon attack with both shield and sword each turn for no added penalty. With the talents, then:
For 2 Advantages or a Triumph, he can hit with both weapons, doing basic damage for each.
For 4 Advantages, or a Triumph and 2 Advantages, he can knock his opponent prone (with the basic shield's Knockdown quality) and hit with both weapons.
For 6 Advantages, or a Triumph and 2 Advantages, he can stagger his opponent with Shield Slam and hit with both weapons.
If I pick up Dual Strike, too, I can trade in 2 Strain for 2 Advantages to ensure a double hit.
The question is: Is this all worth it? Is the versatility of imposing Knockdown and/or Staggered each turn worth the investment in talents or the upgrades to the shield? Or are those two-weapon-combat talents not worth it for someone fighting with sword and board rather than a pair of swords or some other combination?
