Necro lvl 15-16 struggle

[Tenloar]

Personally I can tell you I enjoyed that level range in Oasis.

I was only killing undead and brought out the Undead spell kit that consisted of Ward Undead, Sense the Dead, and Spook the Dead.

Only DoT I would add to them was Engulfing Darkness, other than that I'd just nuke away with the Undead DD (I also love the -Magic component it has). Obviously keeping Dark Pact up and having Lifedraw up for health.

Super easy and safe EXP, goes much faster with Clarity and if you can get a Magician to summon you a Staff of Symbols/acquire a Rusty Halberd from a merchant also makes your pet hit for 20 dmg per swing.

Hope this helps!
