he needs a spell to strengthen zombies stats, an ultimate to make undead that die come back to life as well as making fallen enemies reanimate, undead explosion and zombie fusion are things i would want if i was a necromancer
you should implement the martial realms of second coming of gluttony it is a good technique not as crazy as a technique from chinese novels but it is a very good state of mind/technique if you use any type of weapon
Acho que seria interessante ele investir em maestreia nas suas habilidades e na eficiência de energia e também aprender usar de forma variada sua necromancia
