I think a true striking rogue has a decent shot at this.
Crossbow one?
I think a true striking rogue has a decent shot at this.
It depends on what you mean by "martial", what you mean by "caster", what you mean by "outdamage" and whether you are talking about a specific level or all levels.
Relevant questions:
1. Is a martial any character who has martial weapons proficiency or is it something else.
2. Is caster any PC that casts spells (i.e. is a Paladin a caster and also a martial?).
3. Are you talking about a specific caster or any caster and a specific martial or any martial. In another words does the strawman martial I need to propose just have to beat one caster or do they have to beat every possible caster build?
3. By "outdamage" do you mean at 20th level specifically, at another level specifically or at a number of levels from 1 to 20? In other words if a "martial" "outdamages" a "caster" at more levels than the caster outdamages that martial does that martial "win". Further no single class is the best at any specific level, so if the martial I propose is the best at 4 different levels, and no other class is the best at that many levels, but there 5 different casters that are the best at 3 levels each does that mean the martial "wins" because it is the best at 4 levels, where any specific caster is only the best at 3 levels.
Caster is primary caster level 9 spells and multiclass. EK10/Wizard 10 more caster.
Half casters are martials for these purposes. Can a pure caster win vs anyone else and when.
I think a true striking rogue has a decent shot at this.
Ok then, assuming you add Charisma bonus at your table I think a Warlock beats martials at level 2-6 using Pact of Blade, Green Flame Blade-Agonizing Blast, Truestrike-Agonizing Blast, and Hex, Cleave at level 4, and at levels 5-6 that plus investment of the Chain Master with an Imp familiar.
At level 5-6 using Green Flame Blade, peak damage you are looking at 1d12+strength(Greataxe)+1d6(Hex)+1d8+charisma(Fire)+1d8+charisma (secondary fire)+1d12(Cleave)+3d6+3(Imp)
So 2d12+2d8+4d6+13
You don't get both the Hex damage and the Imp damage every turn because they both eat bonus actions, but I included them both.
A multiclass based on the above, if counted as a caster will make that higher and probably extend it to a lot of levels, I like Rogue for that though and using a 1d8 finnesse weapon and pushing Charisma instead of Strength.
Part of this is the Warlock has a combination of damage types that is going to bypass a lot of different resistances.
Pact of chain doesn't scale well but at level 5 it's great.
I find it scales pretty well, mostly because familiars are allowed to take the magic action. So you can give them magic items like a Wand of Fear or necklace of fireballs or an elemental gem. They can also administer potions and it does not cost you any actions for them to do any of that.
Although Imps do the most damage, I find Quasit's are generally the most useful and they are better if your Warlock gets Inspiring Leader, which gives them a bunch of temp hit points.
