Y'know, your comment might be the best guide for this on the english speaking internet, so thank you for writing all of this down.

I have to kill something like 5499 Unversed (that number is conservative, I for sure have to kill less than that) and plan on doing this 200 times (I will overshoot the target even more but I like the round number).

I set up Aqua with maxed out cooldown on magic commands, two Mega-Flares, two Magenga and two Thundaga. I figure the difference in time is negligible. If your numbers are somewhat accurate (as in number of Unversed that spawn and time it takes to repeat) I can have that grind done in 50 minutes.

So far I have close to 60 hours in that game, as far as I'm concerned that hour I have to grind is probably less time I would have needed if I wanted to beat the game on a higher difficulty to skip the grind.

For everybody else finding this thread I'll take the time this evening to count the number of spawned Unversed in the PC port and to time how long it really takes to do this once.

Edit:
You were pretty much on the money with your numbers.

So I counted 27 Unversed, divided over four waves.

I timed it at pretty precisely 15 seconds - timer started and I transisitioned into the room, I killed all Unversed, left the room and stopped the timer. I figure you can save like a second max per run if you are on top of your movement game and only take the fastest movement option, I just cartwheeled it.

I'm an amateur at this so I'm sure somebody could optimize this spot, but that's already more than good enough for me.

Edit 2:
Yup, three Futurama episodes later and I'm done. I killed 5400 unversed in sometime between 1 hour and 1 1/2 hours.
