My DM is using this homebrew version of True Strike - too powerful?

[Man_Over_Game]

My thought process was:

"The next attack against that target gains a bonus to attack equal to your Proficiency. You can also spend your Bonus Action this turn to make a melee or ranged weapon attack against that target".

That's a balanced cantrip, one that isn't only good for doing one thing and one that isn't going to be spammed every friggin' turn. It also can't be easily abused by Quicken Spell or other shenanigans.

Make it powerful, versatile, but at a cost.

There's also no point in complicating things by adding a ton of annoying 1d4s. RNG is already applied through the attack roll, so there's no need to overcomplicate it more than that.
