Hi there!
I know it's been a while since Firelands solos started, but anyways, I've mage a video guide on how to do it effectively and easily as a Fire Mage!
Introduction:
This is a way where we focus on the big Fire elementals' (Pyrelord) smaller adds, which is basically the most profiting way to solo nowadays. There are a total of 5 Pyrelord packs, and 3 smaller adds at each pack, making a total of 15 small adds.
The video will show you the path where you should kite them and a few more information. (the text goes fast thou, you'll have to pause it for a few seconds, I didn't want them to disturb the kiting area)
If all is done well, you will kill the adds from 3 to 7-8 minutes (depending on luck of combos and combustion) with 1 pyrelord and 15 small elementals dead.
Preparation:
-Get any of the "Minor speed increase" enchants on boots, it will give you +8% walking speed.
-Get Glyph of improved blink
-Never use Blastwave as it slows the little ones, but not the big ones, you want them to Stack! Use Flamestrike instead
-Get Someone with a Firelands save from, or past Shannox
-Engineering Rocket Boots Extreme can help (Beware of the belt enchant, always be sure to have IB ready when you use it as it may backfire)
