Need some flaring fists?

Apparently 1618 allows your fists to flare.

I'm getting used to UAC and forget that you need to punch/kick/grapple and not just use attack. Sometimes I'm just smashing my fists into things, but I found out that you appear to get flares from your empty hands if you simply just swing your fist for an AS attack.

Code:
You swing a closed fist at a vesperti!
  AS: +291 vs DS: +212 with AvD: +19 + d100 roll: +94 = +192
   ... and hit for 26 points of damage!
   Torn muscle in the vesperti's left leg!

 ** Your hand surges with power as grey luminescence coalesces around it! **

   ... 10 points of damage!
   Plasma lashes the vesperti's shield arm blistering flesh.
Roundtime: 2 sec.
Not sure if this is known or not, but I though it was interesting.
