20's are kind of a weird time for Necros. in your early thirties you can start soloing some guards, like in EC and in the karanas. in your twenties grouping is the surefire way to get exp, like at MM pond. Solo wise though you can make the best exp especially because you start getting your rhythm in your twenties. As an ikky i didn't have to worry about faction really, and the weaker ogres in Timorous Deep and the Giant Skeletons in Rathetear Mtns are good ways to really dig into your mechanics.
If you do Giant skeletons, try planting your summoned/charmed pet at the Gypsy camp and pulling to there. fear kiting will probably get you adds if you do it starting on the mountain. its a good way to work on your charming/fear kiting mechanics. If you do ogres in TD, start with the one on the mountain by the beach and work down the shore line (DONT TRY THE ONES IN THE HUTS YET). It's not a camp you have to break, but youll see how they start to spawn one after the other and youll have little down time, which will help when you do have to start breaking camps.
Necromancers are, imo, the strongest solo characters, but can be a ton of fun in groups besides just being a mana battery.
