RAW, it is an option regardless of your opinion on the matter. Every class has access to the feat. If you want to make a Warlock with Pact of the Blade and Cleave Weapon Mastery, go nuts. It may be more useful for College of Valor Bards that most other non-martials.
"Eldritch Knight Fighter can use True Strike or any other Wizard Cantrip they know instead of one attack during an Attack action."
So you dont need the feat also, you cant swap an attack for a cantrip until level 7, and you can only do it for 1 attack, not the extra attack, and by level 11, youve got 3 attacks, and only one can be truestrike.the other 2 (and the cleave attack) will have to use dex or str.
You don't need the Feat as an Eldritch Knight. You can swap for a Cantrip once per attack action. That is what I said, "instead of one attack". True Strike will use Intelligence in most cases with an Eldritch Knight. The other attacks will have to use Strength unless you found a Finesse Weapon that also has the Cleave Weapon Mastery. Alternatively, an Eldritch Knight that dipped into Warlock for Pact of the Blade could be leaning heavily into Charisma (and multiclass cantrips are weird). There may be reasons to sacrifice the bonus to hit in order to deal radiant damage (including up to an extra 3D6 Radiant Damage), if you're looking to Cleave, you probably are fighting multiple, hopefully lower-level enemies and their AC drop might match your hit chance drop.
Shillelagh from the origin feat, letting you choose your spellcasting ability, leads to some really crazy op builds.
Shillelagh can't be cast on weapons with the Cleave Weapon Mastery, which is what we are discussing here. True Strike and Cleave. If Shillelagh could be cast on the haft of a Halberd for shenanigans, Shillelagh would be relevant here. Maybe in the future.
Good, we agree that Cleave can trigger off of True Strike and there are scenarios where someone can cast True Strike and has Weapon Mastery. Polearm Master has no bearing on resolving Cleave triggered from True Strike. The actual values of Strength versus Intelligence have no bearing on resolving the scenario.
The consensus has already been reached that the Cleave attack wasn't affected by True Strike and that was the expected result when I asked the question originally, but I thought it was useful to talk through the scenario in case a different outcome was reached or interesting talking points came out of it.
"and there are scenarios where someone can cast True Strike and has Weapon Mastery"
Well you revealed it was a fighter/eldritch knight and that was one of the classes i mentioned.
No, you didn't. You literally said that True Strike cannot work with Extra Attack and that you have to choose True Strike or benefitting from Extra Attack. I was the one who mentioned Eldritch Knight.
To be clear, we are not talking about a question regarding an Eldritch Knight in a particular game, a Valor Bard with the Weapon Master feat, or anything else. There is no player. There is no build. I was having a discussion about another topic and thought of this scenario and was curious what people thought the resolution was. It is a hypothetical situation. That doesn't really matter. I don't care how rare the scenario is. I only care what people thought about it. It works in RAW. The question was how. The question was answered a page or two ago.
If you want to try to argue the position that it should carry over the effects of True Strike to the Cleave, it is sometimes useful in debates to argue a contrary position and it may add something that has not been covered already. Someone once told me that if you can't debate the opposition's position, you don't understand the argument. However, I did not find much ground on that side of the argument to work with.
"When I use True Strike with a Cleave weapon and hit, how do I use to resolve the additional attack from Cleave?"
(1) Cleave is a weapon mastery property. Only Barbarians, Fighters, Paladins, Rangers, and Rogues can gain and take advantage of weapon masteries.
(2) every one of those classes get ExtraAttack except Rogue. And TrueStrike doesnt work with ExtraAttack.
You never mentioned Eldritch Knight and only mentioned that True Strike doesn't work with Extra Attack. You are wrong about saying you ever mentioned Eldritch Knight, you were wrong about the only way to access Weapon Mastery is certain classes, and you were wrong about True Strike never working with Extra Attack. None of that was the question of this Topic. Extra Attack never mattered for the original question. Optimization never mattered for the original question. If you want to debate those points, feel free to start a topic on the subject. I would recommend the Tips and Tactics forum for questions regarding optimizing True Strike with Extra Attack and/or Cleave.
Do you have anything new to add regarding resolving the Cleave attack triggered from a True Strike attack, and only that topic, that hasn't already been said?
None of that was the question. However, both are wrong.
(1) Anyone can take the Weapon Master feat to get access to one weapon mastery which they can change out on a long rest as normal.
(2) An Eldritch Knight Fighter can use True Strike or any other Wizard Cantrip they know instead of one attack during an Attack action.
