Your passage is intriguing, and I've proofread it for you. Here are the suggested corrections:
"Ace, DUCK!!"
Ace, heeding his sister's warning, ducked his body and watched as a thick ball of blood flew over his head. The blood, ignited and ready to explode, blew up upon touching the ground. A few of the Screamers suffered burns and severe wounds with blood seeping out of them.
Cherry quickly sprinted towards them with her hands drawn out, black steaming blood rushing towards her. With her hands by her sides, Cherry gathered the black blood and created small blood clones in the shape of the Screamers.
The clones ran ahead of her, their hands turned into sharp blades which were swung at the Screamers. Despite this, the Screamers broke the clones with one strike of their claws, none of them getting hurt in the process.
"What are you doing?" Ace wondered, clearly failing to see the point in the attack. "It's clearly not working."
