Chant

This spell allows you to bolster your allies and hinder your foes. Every ally that can hear you within 30 ft of you gains +2 to attack rolls and saving throws, and every enemy subtracts 2.

While casting this spell, you cannot cast any other spell that demands a vocal component without breaking concentration. The effects of this spell continue so long as you have concentration. Concentration also ends if your capability to use your voice is taken away.
