Vudho is an addon for healers though I know a few tanks who use it too.
As a “casual” I thought I’d show how I use it and the spell layout that I have.
To start, get the addon; maybe from Curse.com
Will give you Vudho Options, this is where you can tinker with the machine. Click on the image to get the full size.
This will give you the “move stuff around” options and the “get rid of stuff” options.
I “drive the train” by using my WASD keys, my thumb can drop onto the Alt key for another set of spells!
My Alt keys are the second layer of my spell-casting. I used Healing Touch a lot more in MoP since it was part of our tier set. You can see Nature’s Vigil is grayed out — that is because I don’t have that talent chosen right now, when I do choose that talent; this is how I activate it.
Finally, the Shift key. This is not as easy to click, so I have very little over here.
That is all there is to it!
If a player is dead and you click on their pane, by default vuhdo will cast either the revive or rebirth spell. By default, if someone is cursed (or whatever), the color will change on the panel. By default, you can move your panels out of combat, but not while in combat.
That is all I do! I saved my profile under my healer’s character name. Obviously I am only using maybe 10% of what this powerful tool can do; feel free to tinker, change stuff around and go as deep as you please.
But, as a casual raider, this is my Vuhdo set up and it serves me well.
