How to Find Spell ID's
 

Hello I hope this is the correct place to post this. I was just curious as to how I can obtain the ID for a spell? I tried looking on WoWhead and Thottbot but they don't seem to list the ID's for the spells, unless I am just missing it which is quite possible xD

Cheers,

Thanks for the response, is there a way to do it in-game with like a hover macro that prints the ID in chat? I wanted to avoid having to download an addon for it (I should have mentioned that first, sorry)

Nvm, I found out that the spell ID is actually in the URL of the spell on WoWhead. Thanks for the help though ^_^

If I remember correctly, going to a URL on wowhead.com and searching a spell and finding it, has the spell ID on the end of the URL.

I.E. http://www.wowhead.com/spell=133 Fireball Rank 1's SpellID is 133
http://www.wowhead.com/spell=42891 Pyroblast Rank 12's is 42891

On various data sites, they'll have the SpellID in the page URL.

WoWHead: http://www.wowhead.com/spell=8690
ThottBot: http://thottbot.com/s8690
ZAM: http://wow.allakhazam.com/db/spell.html?wspell=8690

In-game macro (only on spells you know)
/run print(GetSpellLink("Fireball","Rank 1"):match("spell:%d+"))

There are various addons that allow you to look up spell IDs.
I personally use one I wrote last year.
