True Strike

Since I’m making a weapon attack I can apply mastery effects to right? So if I have mastery with a warhammer and add Repelling blast to true strike, using the warhammer for true strike then pushes the target 20ft away. Is that right?

 Possibly. This is definitely "ask your DM" stuff.

If one looks at it abstractly, just slapping a bunch of effects on the target and then applying all of them, then yes. You have two "push 10 feet" abilities, so you get pushed 20 feet.

If you think of them as being applied fully sequentially, then one might conclude that, after the first 10-foot push, they're no longer there to be pushed again.

If you're trying to apply the mechanics through a lens of realism, or at least verisimilitude, then you can probably reason it out either way.

Thank you!

Push says - up to 10 feet straight away from yourself

Repelling Blast says - When you hit a creature with eldritch blast, you can push the creature up to 10 feet away from you in a straight line.

So based on those definitions, the answer is no you can't push them 20 feet.

It is but 10 feet from you.

I understand Agonizing Blast an invocation is cast on true strike which has true strike cast on a weapon..

You cast true strike (spell) and attack with the weapon, and then use the invocation to add more damage.  I wasn't sure if one can do all three "actions".

Agonizing Blast is not something you "cast" or "use" on its own. It's a passive feature that modifies a specific cantrip when you cast it.

True Strike is not something you cast "on" a weapon. It's a spell that includes a weapon attack as part of its casting, like Booming Blade.

There are not three actions here. There is one action: the Magic action used to cast True Strike.

When I started a few months ago or maybe a year ago, I asked on this forum and understood that casting true strike and attacking with the weapon are two separate actions that create a single damage roll.   Basically the opposite of what is said on the previous page, it is weapon attack that includes a spell cast on it.

Now I am more confused how Agonizing Blast can be used with true strike.

When I type in agonizing to find the 2024 rules (no access to my hard copy book) I get this:

Agonizing Blast

Prerequisite: eldritch blast cantrip

When you cast eldritch blast, add your Charisma modifier to the damage it deals on a hit.

I don't know who told you that, but that is not how it works. You may be thinking of spells like Shillelagh or Magic Weapon, which are cast on a weapon and modify future attacks made with that weapon, but don't include an attack themselves. True Strike does not work that way. If you read the spell description, you'll see that the spell itself includes making an attack with a weapon, much like Booming Blade or Green-Flame Blade. It is a single action.

That is the description of the 5e/2014 version of Agonizing Blast, which only applies to Eldritch Blast. The 5.5e/2024 version of Agonizing Blast has you choose a single cantrip to apply it to. In both cases, it is a passive effect that increases the damage of the cantrip it applies to. In neither case is it an additional action or something that you "cast" on its own.
