Battle Magic. When the Zhentarim Boss uses their action to cast a spell, they can make one weapon attack as a bonus action.

Spellcasting. The Zhentarim Boss is a 9th-level spellcaster. Its spellcasting ability is Intelligence (spell save DC 14, +6 to hit with spell attacks). The mage has the following spells prepared:

• Cantrips (at will): blade ward, vicious mockery, minor illusion

Song of Rest. The Zhentarim Boss can perform a song while taking a short rest. Any ally who hears the song regains an extra ld6 hit points if it spends any Hit Dice to regain hit points at the end of that rest. The Zhentarim Boss can confer this benefit on itself as well.
