Warlock's Wrath feat & Turathi Highborn paragon path

[Venthrac]

In the Turathi Highborn paragon path, there's the following benefit:

Kneel Before the Turathi (16th level): When you hit with an attack benefiting from your infernal wrath racial power, you also knock the target prone.

Since the Warlock's Wrath feat replaces Infernal Wrath with something else, is it safe to assume this would be of no benefit to a Warlock that had the Warlock's Wrath feat?

... is it safe to assume this would be of no benefit to a Warlock that had the Warlock's Wrath feat?

That's correct. Though, I suspect most DMs would allow you to come up with your own level 16 feature (or steal one from another PP).

Knocking each enemy that attacks you prone, on top of the fire damage, might be too much to ask for... perhaps the DM could let you select one enemy that you could knock prone as a free action?
