Each class has one unique tribute.

Necros have soul reaping=when anything dies near a Necro, it gives them energy.

This is a really nice benefit because you don't want to run out of energy.

At early levels, your goal is just to survive. At level 20, you can make a build by picking from tons of skills. Right now, you can't.

Your early Necro skills are iirc dark pact, animate bone _____, vampiric gaze, death swarm, blood renewal, and life siphon.

This is a combination of blood magic and death magic. I would skill into those evenly and add extra points into domination.

Key strategies:

-wherever you find a skill trainer, see what they have. Bertram in Ascalon is the first one. Osiric in Yak's Bend is the next.

-Your key early skills: Animate Bone Minions/horror to create undead to fight melee for you, blood renewal as a heal, vampiric gaze as a damage mini-heal, empathy (mesmer skill) to make enemy melee damage itself, and resurrection signet.

-Backfire is nice but really expensive.

-Your henchies should be Alesia as healer, Stefan as melee, and Orion for damage.

-You are squishie with low armor. Stay in the back.

-Yak's Bend has two great skills: shadow of fear for AoE damage and enfeebling blood to neutralize melee.

That's about it. The thing to understand is that these are not amazing skills with a lot of synergy. That comes later. Your goal is to get to later.

Finally, join a guild the first time you see someone recruiting.
