Azulk's Necrotic Power

You cast an inky grey beam from your fingertip and it takes 1 of 3 forms

Melee Variation: You cast this at yourself. Skeletal armour forms around you giving you an armour class of 13 + your dexterity modifier and 2 bone scimitars appear in your hands which are magical weapons and you use your spell casting modifiers for the attacks and damage. These disappear when concentration ends.

Summoning Variation: You cast this at the ground. You can summon undead creatures on unoccupied spaces you can see within range. Choose one of the following options for what appears: One undead creature of challenge rating of 2 or lower, two undead creatures of challenge rating of 1 or lower, four undead creatures of challenge rating of 1/2 or lower, eight undead creatures of challenge rating of 1/4 or lower. A summoned creature disappears when it drops to 0 hit points or when concentration ends. The summoned creatures are friendly to you and your companions and obey your command which requires a bonus action to do. If no command is given, they do nothing. These disappear when concentration ends.

Ranged Variation: You cast this at a hostile creature. The target must make a constitution saving throw or take 6d10 necrotic damage on a failed save or half as much on a successful save.
