Move Creation Workshop

[Amaterasu]

There's no "area utility" proficiency, so for the 2nd move I'm not sure if it needs anything. It's not exactly offensive or defensive. In case it's not obvious, these are not aimed directly for combat use, although the latter could be used to help assassinate someone. I think the rules are fair, but I'd like some input. My aim here is to have "cheap" utility skills. So, should they cost more than 300, I'd rather nerf them down to the 300 baseline. And if possible avoid the need for any proficiencies or powers. 

(for reference, the current restrictions mean these can only be used in Dane's base form, which has the stats: ATK: 1, DEF: 2, SPD: 3, TEC: 5. The alt is ATK: 5, DEF: 0, SPD: 5, TEC: 1)

Muffle (300):
[spoiler]Dane creates an invisible barrier that suppressed sound within a half a metre of himself in an attempt to move silently. So, any noise that would normally travel more than 0.5m from any point on Dane's body is reduced drastically. A twig stepped on will be completely inaudible, anything Dane tries to say, even him yelling, will likely remain. A pot knocked off a shelf, however, will still be heard if, and only if, it falls more than 0.5m away from Dane. 

This effect requires constant concentration, so attacks cannot be charged up, Dane cannot transform or change forms, Dane cannot summon with or otherwise use his Omnilium, and Dane cannot use any other move that requires concentration. He can still move normally, and use any non-ranged attacks that do not fulfill those conditions as well as any movement powers. The barrier primarily works one-way, so Dane can still hear all sound within it, as well as sound from outside. However, external sounds will seem reduced in volume about a third.

Primes with sensing powers will be able to hear the sounds as normal if they know Dane is using the effect, and concentrate on doing so. The effect takes 5 seconds to start (during which Dane cannot move and must concentrate) and will not end unless Dane wills it to (when he can restart it again by concentrating for 5 seconds) or he takes damage and thus loses concentration. If this happens, muffle cannot be used again for 1 minute. A very loud noise (any sound loud enough to leave your ears ringing) can break the spell, resulting in the same outcome as Dane taking damage.

Dane needs at least 2 TEC to use this move. Which currently means it cannot be used in his alternate form (but it might be possible after a stat increase).[/spoiler]
Silent Room(300):
[spoiler]Dane enchants a room, or a space, no larger than a 6m by 6m by 6m cube (20x20x20ft) with an effect similar to muffle. The area being physically enclosed is nice, but not required. No sound, barring the equivalent of loud explosion, will breach it. So, anyone inside cannot hear outside, and anyone outside cannot hear what happens inside. The effect takes 10 seconds to create (during which Dane cannot move and must concentrate) and cannot be moved afterwards unless bound to a mobile "space", such as a train carriage or a car interior. After which it remains as long as Dane wills it. It does not require intense constant concentration to maintain, so its use only restricts Dane's access to using Omnilium and other concentration based moves. It does not restrict the charging of moves, movement, powers, transformations, and the changing of forms.

Some small amount of concentration is still needed, so the effect ends if Dane travels more than 6m from one of the rooms sides, if Dane takes damage, if a very loud noise passes through the boundary, or if a someone else concentrates on removing the effect. This takes 5 seconds to do with a TEC of 5, and reduced by 1 second for each point of TEC above that, and increased by 1 second for each point below. So can be willed away instantly by anyone with a TEC of 10. A prime with a TEC of 5 or higher will instantly notice the effect upon either being inside it or standing within 6m of one of the sides. However, a prime with a TEC of 2 to 4 will not notice the effect unless they walk through the boundary themselves or have a sensing power, a prime with a TEC of 1 or more will notice the effect if they were within 1m of Dane when he created it, and a prime with a TEC of 0 will be incapable of sensing it at all, regardless of if they find out it exists - that said, if they have explosive or are able to make a very loud noise, they may still be able to end it.

Once noticed, the prime will feel "fuzzy" while within 6m of one of the sides and instinctively know how to shut it off through concentration. The method is unique to each individual. Some will picture it mentally as a castle and imagine smashing it down. Others will just yell profanities. And some will just turn it off like flicking a switch. Gestures may be used but they are not required. If someone trying to stop the effect is damaged, shoved, or distracted by any other means, all progress towards doing so is lost. So a prime with a TEC of 5 that focuses for 4 seconds before stopping will have to start again and focus for 5 seconds at once. Any prime with a TEC less than 10 cannot concentrate on any other attacks while trying to end the effect. So cannot charge an attack, transform, use Omnilium, or use any moves with a sensory power as a prerequisite. Basic moves and movement will work as usual.

If the effect if forcibly ended, Dane cannot use it again for 5 minutes. Otherwise, he just has to focus for another 10 seconds.

Dane needs at least 5 TEC to use this move.[/spoiler]

I think that you could use Area Attack and/or Area Shield instead of a nonexistant Area Utility proficiency for the above. I'm not entirely positive on this, though.

Muffle:
-The part that I marked in bold is confusing me a little. Could you re-word it to better explain what you mean by it?
-How draining is the move to use?

Silent Room:
-This one sounds very powerful. I'm not certain if it would be approvable as a regular move or if you would be asked to make it a Super Utility.
-What's the range that this can be casted at?
-How draining is the move to use?

Feel free to repost them if you want another lookover!
