[X] Wait and watch what happens
I'm on team "Hope Cassie is actually Ziz".
I suspect if we unleashed a Ragnarok at the unison device Ziz would just yank it out of the way faster than we can re-aim at the thing, and anything less than that she's already seen it coming and moved a piece of space junk near enough to intercept.
(Fetad made a good point that we should probably TRY to destroy the Unison Device, but honestly I don't want to risk it actually working from an OOC perspective)
As has been pointed out before: She could have stolen it at any point before or after now. Why now? Why when Taylor and Tim are watching? My thought: When she transfers over to the UD she's going to stop flying and start
FALLING and wants someone to catch her.
Most of the time, the only practice a cape with a boost needs is to figure out exactly how and what that boost is going to do to their powers. For MM… Hmm. I'd have to do some thinking about exactly what said boost would do for her. She doesn't have anything that's easily quantifiable.
Easiest answers? (# = ranged, #m = melee version)
1) She gets access to more Tinkertech weapons, things that Masamune COULD reproduce, even if he hasn't started yet. (Tinkertech laser rifles, more powerful tasers, more exotic explosives, less than lethal microwave guns, etc.)
1m) Taser swords, heat knives, variable sword (ala Ringworld), etc.
2) Increase the payload of any weapon she fires (it's basically Green Lantern energy anyway, making a 5.56 hit as hard as a .50 cal Beowulf round is well within the realm of Shard's telling physics to take a hike)
2m) Swords cut better, blunt weapons increase mass just before moment of impact, nets become harder to cut, etc.
3) Weapons now raytrace (IE instant transmission between launch and target) no need to lead your bullets or account for bullet drop. (All ranged weapons become Line of Sight)
3m) Melee weapons feel lighter / have no weight to MM, but have full weight when impacting something. Being weightless may throw off how it feels to her though.
4) Weapons self optimize, if going for a non lethal takedown even a normally lethal shot somehow only disables. Going for a lethal shot? The term "gibbed" applies.
