Astraea's Clarity AXI Challenge rank
One Shot, One Kill.
Thanks to @Astyrrean for the help with picking a build.
Kill a Medusa variant Interceptor solo (alone), spending only 175 (or less) Gauss Rounds in the process, using 3 Medium Gauss Cannons (or fewer).
Basic ammo only
The only allowed source of hull damage for the Interceptor are your Gauss Cannons. (No ramming, no SLFs, no using human weapons to chip at the hull...)
