Shouldn't that damage be 1d8+2(str mod)+3(attack die)?Because the attack die came up a 3, the Deed also succeeds. The warrior does 1d8+2 damage with his longsword
Also, in the paragraph above that it refers to the attack die as the action die. It's confusing.
If the action die is a 3 or higher, and the attack lands (e.g., the total attack roll exceeds the target’s AC), the Deed succeeds. If the action die is a 2 or less, or the overall attack fails, the Deed fails as well.
