Wookiee Roar 1 (Source)
/wookieeroar is a conical intimidation (unsure on the duration of the effect, but it is most likely on par with /intimidate1)... it can only be used once every 5 minutes... and it provides a small mind buff, usually only +20 (i believe this is tied in with the number of opponents you successfully "roar" - i've had the bonus be as high as +80)... also, it seems to work outside of the combat queue, activating immediately...
it does seem to stick with more regularity than /intimidate1 (at the novice brawler level), but after you get bonuses to intimidate through clothing or master brawler that may change... one thing you might want to do is create a macro for /wookieeroar, i've had trouble with the premade "button" not working correctly after long periods of playing...
now that i'm a brawler again, i mostly use /intimidate1 when soloing or fighting only 1 critter... /wookieeroar is sort of a last-ditch effort on my part, and because of the timer i usually save it until i really need an area intimidate... regardless, even with all the other clutter on my toolbars, my button for /wookieeroar is up there and will forever be... he
