Lighting the Beacon

I just got done doing this and it was harder than some map bosses. There were so many blue ghosts, all of them with different Archnemesis tags, and all of them with at least 4 tags. I was even running Cremation and had all of my Armor Brands down, and I could not kill them fast enough. It was a freaking endless supply of blue ghosts. I had to have killed 30-40 of them by the time I finished it, and this was on the last bend alone of the challenge. Lvl 50 in a lvl 50 zone. I'm running 2 crafted wands (+15-27 fire damage), with almost 1400 hp and over 500 energy shields. This should not be harder than Kitava. Yet I died 4 times fully out of mana and health pots.

I'm even leveling with one of the strongest leveling setups for a fire caster. The blue mobs were way too strong and they coming at you fast. Normally these guys are fodder for the more dangerous Flamethrower cannons more or less, but this time they were all very deadly tanks moving at high speed on top of the flame thrower cannons.

Absolutely absurd for act 6.
