Heroic: Alysrazor

For anyone who just zerged through quests without reading, the reason the achievement for killing the Fire Hawk Alysrazor has a picture of a green dragon is that Alysrazor used to be a green dragon, one tasked with guarding the imprisoned Fandral Staghelm. And we all know how THAT ended up.

The diffrence from normal to heroic is that she gets a new ability called Firestorm , and she will summon an add called Herald Of The Burning End. The Firestorm is cast about every minutes , if i remember right. The ability does 100k damage each second that doesnt line of sigh the ability. to LoS this ability you need the Herald of The Burning End , which will spawn in the middle of the room. He will cast Cataclysm , which does 50k damage to people within 5 yards of him. After this he will kinda morph into a meteor , which has has around 150-160k health in 10 man. It can do into 1 of the 8 random directions , towards a wall. You dont want it to hit the wall of it'll explode and do quite alot of damage. The meteor will create a LoS to block the damage of the Firestorm. Also , the hatchlings will has around 9-10m health now , BUT , you gotta kill it before a firestorm , or it'll cleave your raid , which'll also wipe your raid. For the rest the things are usuall for heroic: more health and more damage. The tornadoes will hit you for around 70k , meaning 2 ticks is enough to kill you , instead of 4 on normal.

you can use snares on the meteor's when they spawn. makes stopping them very easy
