trying to make a spell with an item

[drumminforev]

i am trying to make a spell where when a hero aquired this item this is what happens..

the item will have a spell of doing area dmg, and have a 20 second cooldown, and every time the hero is attacking, when the cooldown it up, it automatically casts that as his attack instead, and then back to normall attack until the cooldown is up again.

can anyone help with specifically what i should do.. specifically.
