War Chant

“Let this embolden you all! Let the might of this army be increased tenfold! The gods of war honor us tonight!”

-Marius the Magnificent 

You embolden and empower all allies within a massive area. For the duration, all allies within range have a +1 to attack and damage rolls and their attacks count as magical for the purpose of overcoming resistances. As part of concentrating on the spell, you must use your action to maintain the chant on each of your turns. 

At higher levels:

When casting this spell at 7th level, the range becomes 500 feet and the bonus becomes a +2. When casting at 9th level, the range becomes 1000 feet and the bonus becomes a +3.
