How to prepare for ragnaros.

[Felbane]

There is a lot of things one can do to temporarily increase one's performance.

usually this is a waste of time and money, but sometimes its worth it.

Versus Ragnaros, its worth it.

Below is a list, off the top of my head, of things you can gather to boost yourself.
Either they drop directly, or the fallen have shiny crafters that can make them for you if you bring reagents.

(thottbot nicely lists reagents and all for stuff, its neat.)

All classes:

juju ember. (+15 fr for 10 minutes)

Lung juice coctail. (+50 stamina for 60 min. stays on if you die.) Only one buff of this type can be used at a time.

Greater fire resistance potion (absorbs a LOT of fire damage)

gordok green grog. (+10 stamina. buyable from the drunkard ogre after a completed tribute run.)

Also two very obvious, but extremely useful ones...

please take your time to get at least 10 bandages.
The fight will be long, and we really don't want to waste healer mana just because you couldn't be bothered to bring a little runecloth.
