Create an area to test skills and rotations different than training dummies

[Thurmnmurmn]

If you've ever played Lost Ark, you'll recognize what Trixion is; a training area where you can summon "scarecrow" enemies to practice different skills, tripods, rotations, and literally parse yourself with timers. In Trixion, you can reset CDs and fill your resource meter at the press of a button. It's different than training dummies in XIV since here you have to wait for some skills to come off CD to restart your rotation or try something different.

I've been away from this game for a while so unless I'm mistaken, a resource like this is not available in-game. There may be rotation managers online but I'm referring to an in-game area to test out skills, rotations, and while third party parsers are against TOS, an in-game parser wouldn't.

This is an example of a Trixion parse from Lost Ark. Notice the resources on the right side of the screen where you can reset CDs and fill resources.

You can do what your asking for by entering and leaving a duty to reset your abilities.
That said, being able to bypass that would be nice.
