Change Cooldown of an Item

Hello dear users.

MAybe any1 knows how can i change the Colldown of a rune of teleport?

Or gererally any cooldown from an item?

Greetings.

Change ReqIg in dbo.Items to 0

so if i change to 0 = no cooldown?
And if i change to 600 = 5 Minutes?

thats what u can guess out of the post of murik13 yh
