I was again in one small eq party and managed to get a critical hit with channelball:

You are done with the chant.
You thrust your hands forward and scream 'shar ryo den...Haa!'
The crackling small blue comet slams into your target and explodes in a deafening bang!
You feel like you managed to channel additional POWER to your spell.
The air is filled with pure energy and crackles with power.
Unseen BURSTS of magic are absorbed into the spell!
You watch with self-pride as your channelball hits Skeleton.
You have a new party kill option for top10!
A pixie appears on Atletico's shoulder, whispers something in his ear and
disappears with a tiny *poof*!
Skeleton loses the privilege to live.
Skeleton is DEAD, R.I.P.
**Energy aura refreshed!

This blast gave me 7th spot on the channelball plaque:
