True Strike

[Lowkey]

Should be a bonus action. I could live with the change to this ability, if it took up a bonus action slot, to actually make it useful. Currently using a full action in order to have a minor advantage on hit, is not even worth the spell slot.

*IF* it's going to use an action, True Strike should be a passive where your next attack, regardless of who it's made on, gains advantage, like normal D&D.

I would agree here. True Strike as an action is putting an awful lot of stock on whether the battlefield will even look the same way by the time you get to take advantage of it. Bonus action might be too drastic of a change though. I agree that making it your next attack period would be a welcome change.

It is a cantrip, so useable at will. Allowing it to be used as a bonus action would be massively abusive. It would mean every attack would effectively always have advantage. A rogue would always get sneak attack, a guiding bolt would always be cast with advantage, etc.

Next attack new round is powerful enough. You cast it and then use a massive targeted spell or ability (smite, sneak attack, maneuver, etc.) It is also useful if you have no other attack/action in a round -- closing, folks are behind cover, etc. It is also fine having some cantrips that just aren't that good but which might be useful in a specific build.
