@AtikLYar: Go For the unit weapon I'd wait for the custom model, because we still don't know how the unit will look like. For the blast I used a very similar idea in my own mod: we could make a huge Mothership come down from the sky and use Planet Cracker on the target point.
I added an upgrade to range, although the button doesn't vanish for some reason, the upgrade itself only applies once.... (Mostly because I wanted to use the Tychus Decal as a bit of a 'sniperchick' joke....)
I also got rip of the error that kept coming up when the unit shot, but now the weapon makes no noise.....
As for the fidget decloak, it only happened when the unit would turn, so I just set the turn chance to zero.
I'm gonna take a bit of a break from this one (For some reason I can't figure out, it is impossible to chrono boost the Purification Zone.) so here is the current version if anyone wants to mess around.
I managed to get the upgrade button working properly.
Still gotta do some more fine-tuning on some other parts, although I'm seriously waiting for someone to offer a model or something, unfortunately.
1. The normal nuke system doesn't seem to work that well, expecially considering the unit de-cloaks to cast it.
2. Perhaps a better idea is to have the unit warp in a timed unit in the form of a giant mothership, which you then fly over and have either an instant omg-lazer-of-death, or something more like the original planet cracker, where the beams come down out of the MS while it flies around.
3. I've been thinking the other abilities we could add. One that I recently thought of was a sort of "Warp Step" where the unit teleports into any player-owned powerfield on the map, similiar to how a warpgate makes units.
An Item Kit? Nice... Will have to check that out... maybe now I can make that Uber I always wanted to but had crappy attachments... or maybe an Uber Toss unit... hmm. Depending on what pieces are in the kit.
(1) Stealth Scan - Reveal large target area within  spaces (not across the map, but easily most of a base from just outside of it). This scan does not show the enemy that they have been scanned. [50 energy]
"The highly secretive Conclave have had their eyes on a few Khalai, gifted with the purity of sight, since the beginning of the great war. But their inclusion into the armada means certain laws must be amended.
During the battle of the Judicator council against the invading Zerg swarm, a vote was passed to activate their forbidden weapon: The Protis Snip--
Able to destroy enemies from a far using intense psionic focus, the Protis Snip proved to be an invaluable tool in the defense, during the battle of Kor'shakal.
However, at the last moment, their leader [insert name derived from bnet poster here] decides to turn against the wishes of their masters, and flees.
To this day, they have never resurfaced, nor their existence known to the rest of the Khalai. But rumors have begun to spread about this secretive faction of deadly Protis Snip--"
