Skeletal Mastery and Flesh Golem increase the effectiveness of the necromancer's minions, while Dark Ritual helps ensure that you always have enough resources to use your skills.

As you level up, you can consider investing more points into Summon Skeletons and Raise Zombie to further enhance your army of undead minions. You may also want to experiment with other summoning skills, such as Golem or Revive, to find what works best for your playstyle. Additionally, you may want to invest in defensive skills, such as Bone Armor or Decrepify, to ensure your survival during battles.
