Assuming the other guy was right about you only being level 54 necro, you should not be expecting 2k+ hitsplats.
Necro damage is tied to two factors: damage and accuracy. Damage primarily comes from your weapons, but once you upgrade your armor to T70+ and pick the (Power) upgrade path, you will additionally gain damage bonuses from your main armor slots as well. You can also gain damage bonuses from neck (I recommend an Amulet of Glory if you're poor), pocket (do the City of Um tasks ASAP if you have not done them already; the reward is very good and also will boost your necro damage when equipped), and ring slots, though I'm unfamiliar with what a good beginner ring would be because I just use 6th Age Circuit for everything, and that's anything but a beginner ring! There is a Fight Kiln cape for necromancy, but you shouldn't worry about that until you're at least 75 necro.
So start by upgrading your weapons and armor to T50 if you haven't done so already, and keep them up to date as you continue leveling necro. On the side, get an Amulet of Glory and do the City of Um tasks.
Accuracy is a bit more finicky than damage. It's tied to your weapons, and somewhat to your armor as well (though armor cares more about the "Necromancy" tag than anything here), but it also increases with your necro level. And of course, some monsters are weaker to necro damage than others. You should not be expecting 2k+ hitsplats until your accuracy is at 100% or close to it against your target of choice.
Otherwise, keep on grinding. Like Riko said above, there's a HUGE power spike once you get to T70 armor and weapons. Don't worry too much about hitsplat numbers until you reach that point.
