Custom Feat: Master Duelist

[Yunru]

First we need to know what sort of impact Sharpshooter/GWM has, so here's the damage increase from using -5/+10 at any given value needed to roll to hit:
For 2d6+5:

d20 roll needed	-3	-2	-1	0	1	2	3	4	5	6	7	8	9	10	11	12	13	14	15	16	17	18	19	20	Avg
Damage increase	9.5	8.375	7.25	6.125	5	3.875	3.375	2.875	2.375	1.875	1.375	0.875	0.375	-0.125	-0.625	-1.125	-1.625	-2.125	-2.625	-2	-1.375	-0.75	-0.125	0.5	1.65

For 1d8+5:

d20 roll needed	-3	-2	-1	0	1	2	3	4	5	6	7	8	9	10	11	12	13	14	15	16	17	18	19	20	Avg
Damage increase	9.5	8.525	7.55	6.575	5.6	4.625	4.125	3.625	3.125	2.625	2.125	1.625	1.125	0.625	0.125	-0.375	-0.875	-1.375	-1.875	-1.4	-0.925	-0.45	0.025	0.5	2.19

Sorry @BacchusNL, your feat might work well for your intended purpose in your own campaign, but it’s objectively and humongously unbalanced with other published feats. I don’t need to repeat all that was said, it you’ve got two abilities that steal from main archetype features plus a stat boost. Opportunity attacks are relatively uncommon. Sentinel makes them slightly more frequent and reliable, but being able to counter attack every round you’ve been attacked, regardless whether the attack hit or not, is pretty much automatic as soon as you get into melee (regardless whether you did so intentionaly or not).

“ MASTER DUELIST

- Your STR or DEX increase by 1.

- Whenever an attack roll made against you is failed, you can use your reaction to make an immediate attack roll using a finesse weapon against the attacker. You score a critical hit on a 19 or 20 with this attack. Once you use this ability, you must finish a long rest before you can use it again.”

it probably is still stronger than published feat, but it’s a bit more reasonable.

IME Sentinel makes reaction attacks happen nearly every round.

Why restrict this concept to finesse weapons?

Making it refresh on a long rest, in addition to only working with a missed attack, makes the feat much weaker than the feats it’s meant to stand alongside. The point is to have a feat like GWM and SS for one handed weapon users, without just doing the same thing they do. Heck, your feat is in the mid-low tier of feats, at best. Dual Wielder is better, as is defensive duelist. EDIT: maybe. DD is pretty decent in the one thing it does, but is restricted to one weapon type and does nothing else.

@BacchusNL I’d change the wording to requiring a failed attack, and make the crit stack with other crit range increases, to a maximum range of 16-20, so champions have cause to take the feat and use one handed weapons. Past that, the free stat bump is extra, but since it’s a knowing freebie, enjoy it!

Also, it doesn’t steal the BM’s toys, because the BM still does it better, and can benefit from taking the feat. Combined with Parry, this is real fun. Advantage in the attack is too much though. I’d choose between that and expanded crit range.

Also, maybe consider just beefing up Defensive Duelist?

Not really the point of this thread. My GM and me are fine with those feats existing however not a fan of the fact there is no 1-handed equivelant, creating a disparity.
And we've been playing with the feat for a few months now, 0 Issues compared to if I was a sharpshooter rogue.

Lol at the idea you’re messing up your game. I’m not even sure the feat as it is, is any better than GWM.
