Meteorb builds are not terrible, if they are made properly.
I would like to take credit for my build, but I can't really. See
this guide.
Reply here if you have questions
Additional Comment:
I have a level 88 meteorb. Not perfect equipment (expect at least 5k more in damages)
Fire:
Fireball:7k
Meteor:14k
Ice:
Frozen Orb: 450
Do not let orb damage scare you, that is
per shard, although my fire is much stronger and I only use orb for immunes and once on each boss to cold.
What I am missing from equipment:
2x Soj
Torch
Ani
6x Fire gcs
Arachnids mesh
Once I get these (+13 fire, +7 cold) the damage will get higher.
It is up to you if you want to build meteorb. Fire sorcs do more damage but I think that the damage you get with nice equipment and fire is enough, and then merc + ice is enough to deal with immunes.
