What is the Death race based on in the game? - on necromancy (raising the undead). What is the main task of a necromancer for this purpose? - not to cast magic (it is weak compared to other races) and even more so not to fight in melee (to age the enemy), but to survive in battle. Which class is best suited for this? - assassin. And when this build is developed, you can choose whatever you like. But this is my personal opinion, because another player may use other skills and techniques in the game with no less success.
