The unicorn turned, surprised by the sudden change in odds.  I could have attacked her then, but threatening a pony is much different than actually attacking one.  I wasn’t sure I had it in me to slash at another pony, to draw her blood.  To maim, or possibly kill.

The unicorn kicked up the fallen sledgehammer and turned to face me with it, murder in her eyes.  And suddenly, I found it easy to thrust the shovel-spear forward.  I was no longer struggling with following through on a threat; this was survival.  Self-preservation is instinctual; it clears away the moral hesitations.   And while I did not have the fighting skills of my opponent, I did have an advantage all my own.   S.A.T.S.

Aided by the targeting spell of my PipBuck, I sent the spear slashing across her knees, hobbling her.  A second slash, this time across her face, relieved her of her weapon.  The third would be a killing blow...

...except I wasn’t ready to do that.  Not yet.  Instead, I swung the spear around, cracking her across the head with its handle, hard enough to splinter the wood.  The unicorn raider fell at my feet, unconscious.
