True Strike

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.
