Too Late
As Adam landed on the ground, spurting blood from his mouth, he couldn't help but curse inwardly as he felt his ribs crack, Damn it, that didn't go quite as planned!
While he, Edward, and Lisa were battling the Iron Mammoth at close quarters, he cast Dingy Illusion at the last moment to make it appear that the beast had struck its trunk three times to attack them.
However, the truth was the beast had only struck Adam and not the other two. The Iron Mammoth didn't excel in speed but in defense. Edward and Lisa had only pretended to be injured and jumped back miserably.
But Adam had ended up really getting injured.
His entire focus was on ensuring that the illusion of his friends getting hit by the beast's trunk was flawless. This led to him being severely bruised instead.
