Necromancer 2.0

At 2nd level, you add two 1st or 2nd-level Necromancy spells to your spellbook for free. You also gain one free Necromancy spell for your spellbook each time you gain access to a new level of spell slots, provided it's a level you have spell slots for.  You may also summon a tiny undead using find familiar.

Also at 2nd level, your necromantic studies grant you resistance to Necrotic damage. Additionally, when you cast a Necromancy spell using a spell slot, you can grant yourself or a creature within 30 feet temporary hit points equal to the spell slot level plus your Intelligence modifier (minimum 1).
