Bugbear Nercomancer

Brute. A melee weapon deals one extra die of its damage when the bugbear hits with it (included in the attack).

Surprise Attack. If the bugbear necromancer surprises a creature and hits it with an attack during the first round of combat, the target takes an extra 7 (2d6) damage from the attack.

Spellcasting. The bugbear necromancer is a 12th-level spellcaster. Its spellcasting ability is Wisdom (spell save DC 15, +7 to hit with spell attacks). The bugbear necromancer has the following spells prepared:

Cantrips (at will): chill touch, dancing lights, mage hand, mending

1st level (4 slots): cure wounds, false life,* mage armor, ray of sickness*

2nd level (3 slots): blindness/deafness,* ray of enfeeblement,* web

3rd level (3 slots): animate dead,* bestow curse,* vampiric touch*

4th level (3 slots): blight,* dimension door, stoneskin

5th level (2 slots): Bigby’s hand, cloudkill

6th level (1 slot): circle of death*

*Necromancy spell of 1st level or higher

Staff. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 8 (2d6 + 2) bludgeoning damage, or 10 (2d8 + 2) bludgeoning damage if used with two hands, plus 3 (1d6) necrotic damage.

Necrotic Burst. Melee or Ranged Spell Attack: +7 to hit, reach 5 ft. or range 120 ft., one target. Hit: 25 (4d10 + 3) necrotic damage.

Summon Undead (1/Day). The bugbear necromancer magically summons five skeletons or zombies. The summoned creatures appear in unoccupied spaces within 60 feet of the bugbear necromancer, whom they obey. They take their turns immediately after the bugbear necromancer. Each lasts for 1 hour, until it or the bugbear necromancer dies, or until the bugbear necromancer dismisses it as a bonus action.

Grim Harvest. When bugbear necromancer kills a creature that is neither a construct nor undead with a spell of 1st level or higher, the bugbear necromancer regains hit points equal to twice the spell’s level, or three times if it is a necromancy spell.
