The goblin raises its arm towards him, as he prepares his explosive attack. A moment later, a tremendous shockwave, coupled with an incredible amount of force, slam into him, likely sending him hurtling backwards. A massive scorch mark ruins the lawn, between him and the wizard; apparently, a powerful offensive spell, that intercepted his attack, likely both cancelling each other out. The good news is, it appears to ahve knocked the goblin off the donkey, which continues to stand there, placidly, chewing on a flower.
