So I killed a dragon and I find out that I'm "Dragonborn". I traveled to meet the Greybeards and they told me to shout, but I already used my shout. I don't want to have to restart from when i killed the dragon because i found a lot of gold and good items. Any solutions?

You can shout as many times as you want to. It's not a one and done power....

you can use shouts whenever you want. there is no limit

Really, it wouldn't let me shout when i clicked on it I'll try it again, thx

Ok it worked when i clicked z before nothing happened.

There is a cool down timer for each shout, but you can shout as much as you want otherwise. A blessing and Amulet of Talos can help shorten the cool down time

Edit: if your compass' edges are bright and shiny the cool down timer is not done yet.

go to your magic menu / look at the shout section & click on the shout you want to use ................then press Z and you will execute the shout .................you want to Chang to another shout you go back to magic menu / shouts ................pick the one you want

you can put shouts into your Favorites so you don't have to open menus every time you want to change a shout .............PS keep in mind that a lot of other things use the Z button ..............like your racial powers or any other special powers you gain like summoning the Assassin of Old ext
