Mistborn #02 The Well of Ascension

throwing up a line of ash as it ran along the ground. It slammed into the back of Ham's legs. The blow swept Ham's feet out from beneath him, and he cried out as he fell.
    Vin jumped into the air again.
    Ham slammed to the earth on his back, and Vin landed on his chest. Then, she calmly rapped him on the forehead with the end of her staff. "I win."
    Ham lay, looking dazed, Vin crouching on his chest. Dust and ash settled quietly in the courtyard.
    "Damn. . ." Spook whispered, voicing a sentiment that seemed to be shared by the dozen or so watching soldiers.
    Finally, Ham chuckled. "Fine. You beat me—now, if you would, kindly get me something to drink while I try to massage some feeling back into my legs."
    Vin smiled, hopping off his chest and scampering away to do as requested. Ham shook his head, climbing to his feet. Despite his words, he walked with barely a limp; he'd probably have a bruise, but it wouldn't bother him for long. Pewter not only enhanced one's strength, balance, and speed, it also made one's body innately stronger. Ham could shrug off a blow that would have shattered Elend's legs.
    Ham joined them, nodding to Clubs and punching Spook lightly on the arm. Then he leaned against the railing and rubbed his left calf, cringing slightly. "I swear, Elend—sometimes sparring with that girl is like trying to fight with a gust of wind. She's never where I think she'll be."
    "How did she do that, Ham?" Elend asked. "The jump, I mean. That leap seemed inhuman, even for an Allomancer."
    "Used steel, didn't she?" Spook said.
    Ham shook his head. "No, I doubt it."
    "Then how?" Elend asked.
    "Allomancers draw strength from their metals," Ham said, sighing and putting his foot down. "Some can squeeze out more than others—but the real power comes from the metal itself, not the person's body."
    Elend paused. "So?"
    "So," Ham said, "an Allomancer doesn't have to be physically strong to be incredibly powerful. If Vin were a Feruchemist, it would be different—if you ever see Sazed increase his strength, his muscles will grow larger. But with Allomancy, all the strength comes directly from the metal.
    "Now, most Thugs—myself included—figure that making their bodies strong will only add to their power. After all, a muscular man burning pewter will be that much stronger than a regular man of the same Allomantic power."
    Ham rubbed his chin, eyeing the passage Vin had left through. "But. . .well, I'm beginning to think that there might be another way. Vin's a thin little thing, but when she burns pewter, she grows several times stronger than any normal warrior. She packs all that strength into a small body, and doesn't have to bother with the weight of massive muscles. She's like. . .an insect. Far stronger than her mass or her body would indicate. So, when she jumps, she can jump ."
    "But you're still stronger than she is," Spook said.
    Ham nodded. "And I can make use of that—assuming I can ever hit her. That's getting harder and harder to do."
    Vin finally returned, carrying a jug of chilled juice—apparently she'd decided to go all the way to the keep, rather than grabbing some of the warm ale kept on hand in the courtyard. She handed a flagon to Ham, and had thought to bring cups for Elend and Clubs.
    "Hey!" Spook said as she poured. "What about me?"
    "That beard looks silly on you," Vin said as she poured.
    "So I don't get anything to drink?"
    "No."
    Spook paused. "Vin, you're a strange girl."
    Vin rolled her eyes; then she glanced toward the water barrel in the corner of the courtyard. One of the tin cups lying beside it lurched into the air, shooting across the courtyard. Vin stuck her hand out, catching it with a slapping sound, then set it on the railing before Spook. "Happy?"
    "I will be once you pour me something to drink," Spook said as Clubs grunted, taking a slurp from his own cup. The old general then reached over, sliding two of the coins off the railing and pocketing them.
    "Hey, that's right!" Spook said. "You owe me, El. Pay up."
    Elend lowered his cup. "I never agreed to the bet."
    "You paid Uncle Irritable. Why not me?"
    Elend paused, then sighed, pulling out a ten-boxing coin and setting it beside Spook's. The boy smiled, plucking both up in a smooth street-thief gesture. "Thanks for winning the bout, Vin," he said with a wink.
    Vin frowned at Elend. "You bet against me?"
    Elend laughed, leaning across the railing to kiss her. "I didn't mean it. Clubs bullied me."
    Clubs snorted at that
