This is not a great Fracter. It's way less efficient than its main competition, Corroder or Paperclip, which I imagine will still be the go to barrier breakers for the discerning Criminal. Those or Breach, which is a pretty good Fracter too, even if it's inflexible and only works on central servers. Now, all that being said...

HALLELUJAH, CRIMS FINALLY HAVE A USABLE FRACTER FOR ALL SERVERS. SEE YA LATER AURORA, EVEN IAIN DOESN'T NEED TO DEAL WITH YOUR WEAK ASS ANYMORE. CRIM 4 LYFE

Hey, if you want to save yourself some influence as a Criminal, this is your best Fracter option. It's less efficient than Corroder or Paperclip but not by all that much, and those are the top of the line Fracters. Saker is decent, definitely usable. You probably won't ever use the derez ability though, unless you come across a Bulwark or Wotan or something.

In comparison to Corroder, Saker will cost you 2 credits more to install and to break ice will cost you 2 credits more against even-strength barriers and 1 credit more against odd-strength barriers. That's really not a huge efficiency loss if you value the influence more than saving 2 credits on the install and 1-2 credits to break Ice.
