#also rip me not remembering the anit-mystic had an active stage like that

[rottmnt-residuum]

So in the last update that agent threw some kind of ball at Raph and Leo. My best guess is that it's some kind of holding device that traps mystic energy, right? But I got a little confused at the Krang. Was that just what Leo and Raph felt like? I mean that their mystic energy got "sucked away" again, like what Krang did. Also those balls were what they bought (?) from that yokai with the cloaking brooch. Will those have a significant role later on, or will you explain a bit more about them if you didn't already?

*slides in from my self banishment*

Yes! the kraang is basically what they are feeling! a.k.a it's a ptsd episode. You got it in one ;P

You know, i kinda forget not everyone is working under the same base knowledge of the show... anyway! we proceed!

As far as i can tell the hidden city police have a few different ways of detaining suspects. The first as seen in 'raphs ride along' are these:

they're just a less invasive version of cuffs really... consequently, they're also basically useless. perp can still get away and all that, mind you, they can't get out without keys... but that's pretty easily solved

the next type is the anti-mystic device:

these bad-boys suck up spells and absolutely wreck any mystic device within its limited range. barry's cloaking broach shatters and is basically unrecoverable, and as you can see it sucks up the mystic odachi's portal. they seem to just suck up any mystic energy thats 'in use'. so as long as you're not doing anything mysticy you're good

For Residuum, the way they work is that any currently active mystic energy is sucked in and stored, so as long as you keep using your mystics the longer it will keep going. Though it does cap out at around ten minutes, it can only hold so much. At any rate, it's best to not use mystics if this thing (multiple of these things) is on the battlefield, as, if you continue to try, you'll end up with an empty tank.

Depending on how mystical exhaustion works, that could be either mildly inconvenient, or deadly!

as to their significance in the comic... i'd say they'll be pretty significant
