If only someone had worked it out across every level so we could just check out the points where BB changes (<5,5,11,17), since that'd give a best-case for BB.
As it happens, I have those numbers right here. The percentage for each level represents the minimum frequency with which the BB rider damage has to trigger in order for the DPR of a BB Swashbuckler to exceed that of a TWF Swashbuckler, without factoring in the Dual Wielder feat. If the percentage is greater than 100%, it means that the DPR of the BB Swashbuckler cannot be made to equal that of the TWF Swashbuckler at that level, even if the BB rider damage triggers 100% of the time.
Level 1: 93.8850%
Level 2: 93.8850%
Level 3: >100.0000%
Level 4: >100.0000%
Level 5: 26.4850%
Level 6: 26.4850%
Level 7: 43.3350%
Level 8: 43.3350%
Level 9: 60.1850%
Level 10: 60.1850%
Level 11: 15.2449%
Level 12: 15.2449%
Level 13: 26.4850%
Level 14: 26.4850%
Level 15: 37.7150%
Level 16: 37.7150%
Level 17: 9.6250%
Level 18: 9.6250%
Level 19: 18.0549%
Level 20: 18.0549%
At the levels which see the most play (1-10), TWF is dominant, with break-even points above 60% for 6 out of the 10 levels.
Here is an example of the math at level 5. Feel free to point out any errors you think you may see:
TWF DPR at Level 5:
Regular DPR (Main Hand): 0.6 * (avg(1d6) + 4) = 0.6 * (3.5 + 4) = 0.6 * 7.5 = 4.5
Crit DPR (Main Hand): 0.05 * avg(1d6) = 0.05 * 3.5 = 0.175
Regular DPR (Off Hand): 0.6 * avg(1d6) = 0.6 * 3.5 = 2.1
Crit DPR (Off Hand): 0.05 * avg(1d6) = 0.05 * 3.5 = 0.175
Regular Sneak Attack DPR: (1 - 0.4 * 0.4) * avg(3d6) = 0.84 * 10.5 = 8.82
Crit Sneak Attack DPR: 0.05 * avg(3d6) + (0.4 * 0.05 * avg(3d6)) = 0.05 * 10.5 + (0.02 * 10.5) = 0.735
Total DPR: 16.505
BB DPR at Level 5:
Regular DPR: 0.6 * (avg(2d8) + 4) = 0.6 * (9 + 4) = 0.6 * 13 = 7.8
Crit DPR: 0.05 * avg(2d8) = 0.05 * 9 = 0.45
Regular Sneak Attack DPR: 0.6 * avg(3d6) = 0.6 * 10.5 = 6.3
Crit Sneak Attack DPR: 0.05 * avg(3d6) = 0.05 * 10.5 = 0.525
Rider Damage DPR: 0.6 * (0.26485 * avg(2d8)) = 0.6 * (0.26485 * 9) = 1.4302
Total DPR: 16.5052
Except that the bonus action Shove takes place AFTER you use your Attack action, or are we cherry-picking the parts of the Sage Advice Compendium that benefit our characters, and ignoring the rest?I see your Dual Wielder and raise you a Shield Master.
I only snark in self-defense. Whether you intended it or not, your post came across as very snarky. Self-awareness is a good thing!For someone complaining about snark (in regards to a post that genuinely had none), this sure is a lot of snark.
