My Necro could use some help

Ok, well first off i have a lvl 20 Necro/Rang and im started to dislike my ranger job, and now ive come to the part of the game were i can switch my char sec. job. So i was wondering if anyone could help we out with choosing between a N/Mo or a N/W, i plan on soloing alot with this char. and i need some help in which would be a better soloer. and if any1 could, can u give me a good build for it. thankyou in advance.

You can change secondaries after Lvl. 20?! That's crazy!

Well I'm a lvl.19 N/W... I use NONE of the Warrior Skills though... I'd go with Monk. Get a 12 or 13 Death Magic, a 10 Healing Magic, and leftovers go to Soul Reaping... You'll be able to do tons of damage, stay alive, and keep a good Energy Pool throughout. Plus, Having lvl.15 Bone Horrors running around protecting you is always fun...

Yes, you can change secondaries after you ascend.

Necro/monk, I think, is the only job that can farm the underworld solo, or at least the only I've ever heard of doing it, so if you are really intent on soloing, go with that.
