Azar is highly susceptible to pain. Shrike/Swallow works well all by itself.
Crinfild Oil, not diamond dust if you want sword play.
Azar may be a fire mage and he may be resistant to fire, but using a dragon dream bomb amplifies your igni so far it does not matter what his resistantances are. He burns.
Try this.
1. roll back. (double tap "s")
2.drop dragon
3. roll back
4.set yrden trap
5. charge up an Igni
6. when Azar is thrown back from trap into the green gas of the dragon - light him up.
Like most things "resistant" to fire, once you get them ignited, they incinerate just fine.
btw, up to a point, the longer you let a dragon's dream bomb dissipate (spread its gas) the wider and more powerful the explosion. If you wait too long (guessing @10+ seconds) it spreads too thin to work.
There is an island in the C2 swamp that is crawling with undead ... alghouls, graviers. There are also numerous blodzueigers and drowners nearby. I have run around the edges of that island getting everything I could find to chase me. Carrying a posse of 10-15 mobs in my wake, I run down the center of that island and drop a dragon. when I get to the end of the island I turn 180 and roll thru the mobs(keep tapping "w") when I run thru the dragon gas it has been spreading for 5-8 seconds, I snap an igni at the bomb when the mobs have gathered. Bodies, arms, heads, feet, fly everywhere. 1 bomb. 1 spell. all dead.
no sword.
