1: duration of Mirrored persona, and pulse Storm are listed as "instantaneous" but shouldnt it be "Sustained" ?
Personally? I think so, yes (for both of them).
2: static now only Works in Sprites within hosts?
Are you talking about Static Bomb or Static Veil?
Static Bomb is a a resonance version of the Hide matrix action where the Static bomb let you hide from everyone that currently got you spotted rather then just a specific icon that currently have you spotted that the Hide matrix action do.
When it comes to Static Veil you can either target yourself or a decker, another technomancer, an agent or a spirte etc. It will, for example, let the target use Brute Force to gain admin access to a network without increasing overwatch score over time.
If a technomancer had an illegal admin Access to a host, together with his 5 Sprite buddies. Does he gain 3 or 18 OS each turn?
Each persona icon have to gain their own Admin access to the network and each persona icon that use brute force to gain Admin access to the network (rather than spending time to Probe and exploit the network to create a Backdoor Entrance) will gain 3 OS each per turn (unless a Static Veil is in effect on the Icon).
...does IT then mean that a technomancer with a Sprite using static veil doesnt gain any OS from having an illegal host Access?
Yes.
This is one of the few reasons why you would sustain a Static Veil on yourself (or a sprite, agent or decker) that gained an illegal (read Brute Force) access to a network to being with.
Static Veil basically let you (or your target) Brute Force into a network and then keep illegal admin access to the network without risk of convergence within less than a minute (instead you could potentially keep your access for many hours). The alternative would be to spend at least one minute to Probe the network in order to create and exploit a Backdoor Entry.
3: tattle tale can now be used on any Matrix user.
SR5 explicitly clarified that it could only increase the overwatch score of an icon that already had an overwatch score. SR6 leave this a bit more open ended (this is not the only example). It might or might not add an overwatch score to an icon that doesn't have one. Depending on your reading it will still 'just' increase an overwatch [that is already there to begin with].
Then again, overwatch score no longer increase automatically every 15 minutes which mean having a few points of overwatch score is not really that critical anymore.
By leaving out the last sentence it get a lot more ambiguous and by RAW i would agree that you can now cause overwatch convergence on an innocent icon. But to actually cause a convergence to an innocent icon you would have to repeat thread tattletale several times rather than just wait an hour or so... I believe this is actually a deliberate change.
4: not really a question, but Im a big bummed out that the increase (Matrix Attribute) are so much worse than the spell: increase Attribute.
As I read it the Increase Attribute spell can only be cast once per target.
As I read it you can't stack the same spell more than once on the same subject. When casting the Increase Attribute spell you have to choose which single attribute to increase (it is the same spell and you only count the test with most successes no matter if the other instance of the same spell from the same caster affect a affect different attribute).
While Infusion (Matrix Attribute) is a specific complex form for each attribute and you can cast each individual Infusion (Matrix Attribute) on the same target as long as you are casting Infusion (Matrix Attribute) that affect different attributes.
This is still under debate I would say, but if it turn out that rules as intended is the way i just wrote it then this would mean that Infusion (Matrix Attribute) is not really weaker (just different) from the Increase Attribute spell.
Having said that, I am honestly surprised that they didn't take the opportunity to streamline the two - seem to be a perfect opportunity if you ask me :-/
But the threshold is also a lot harder (4 compared to MINUS 1*)
Note that techomancers already (by default and without having to sustain a complex form) have a number of 'bonus' matrix attribute points equal to their Resonance that they may use to increase Matrix Attributes by up to 50% of their base rating (rounded up and with a maximum of +4).
Infusion of Attributes is then added on top of this.
This is basically akin to several power points worth of a matrix attribute version of the Adept power "Improved Physical Attribute" (default ability that all technomancers have) combined with several instances of the spell "Increase Attribute" spell (where each instance is a different complex forms which mean they can affect more than one matrix attribute at the same time).
