The giantess predictably took a step backwards with her right leg, which left her in a less than optimal position for her right-handed downwards strike with the hammer. Killstreak took advantage of her painfully slow movement to let go of the remains of the bottle as her leg passed backwards, and retrieved the Evertorch and one of his revolvers from his inventory in it´s place. What was so special about it? Absolutely nothing, at least not where Killstreak came from, but to people from this world, an eternally burning torch? Yeah, plenty special. With the torch in his left and gun in his right, he was ready for his next move. 

The giantess was now in position to begin her downwards strike, and Killstreak let her pull back before utilizing the Evertorch in a particularly devastating move. Flicking it casually against her right ankle as he strolled forward past it, placing himself two meters behind her by the time her slow-mo hammer connected with the ground, and her leg lit up in fire, provided she didn´t somehow move her leg to avoid the torch as it gently made contact with it. Whisky, was, after all, just as flammable in Killstreak´s world as in hers, if not more, as fire was an element created by flaming and raging. Alcohol, especially whisky, made people and objects angry, therefore making it flammable. 

Her hammer met the ground, cracking it apart like it was brittle glass. Killstreak raised his gun. Two well-placed shots towards the back of her knees should provide additional leverage to convince her already substantial downwards momentum to topple her massive weight downwards. He pulled the trigger, twice.
