[RPG] Where was the Thirsting Blade warlock invocation officially published


As title says, where was the Thirsting Blade warlock invocation published? Is it from an official 5e book?

I'm trying to make a Pact of the Blade Hexblade warlock with Thirsting Blade. My DM isn't sure if it is legal so I need to find the source to use it.

The Thirsting Blade invocation is from the Player's Handbook (PHB).

The Thirsting Blade eldritch invocation for warlocks appears in the list of invocations in the PHB, on p. 111:

Prerequisite: 5th level, Pact of the Blade feature

You can attack with your pact weapon twice, instead of once, whenever you take the Attack action on your turn.

It also appears on p. 50 of the SRD.
