Q45 If a Necromancer wizard casts Animate Dead as a 3rd level spell, two undead are raised. But with 4th level spell, how many undead are raised? 5th? 6th? Etc....


And Q45b What is the maximum number of undead a necromancer can raise at 20th level? (Not counting that one boon that gives a second 9th level spell slot)
