Lodged in your face was a snowball, it was wet and it actually quite hurt, considering Ajax threw it directly at your face---

"Hey comrade! Are you just gonna stand in the open like a target or continue our snowball fight?"

With a hushed sigh, you rolled up some snow and tossed it at Ajax. It hits his snow fort instead — which seems to be the pattern of your projectiles. You are only able to hit his ankles or the ground, missing his body and limbs in the process.

It's probably from the sheer cold, it's messing up your trajectory!
