Need help with an exploit

[infinotrix]

So, I figured out that on Crusadegaming.net's private server that if you equip [url*=]http://www.wowhead.com/item=50351[/*url] and unequip it you gain 1 charge, you need 7 for it to proc and it isnt supposed to add charges by equip/unequiping, I know this can be stacked as i have been killed by it.

Someone tell me how this is done.
