Warpriest

Warpriest
For every holy festival held in honor of the Goddess, there have been bloody battles beyond count. For every comfortable cleric in plush robes and high halls, an ancestor who screamed prayers of retribution in the mud and filth of the battlefield. Not all have forgotten the crusades of their grandfathers, for all the tenuous 'peace' with the minions of darkness. The weapons of a warpriest are ready, and their sermons are written in the clash of blood and steel.

Holy War
War is not glamorous, and the goddess weeps to see her children shed their blood in her name, but the defense of the faithful is still among the holiest of duties. Beginning at 8th level, you can attack twice, instead of once, when you take the Attack action on your turn.

Battle Blessing
The bond between brothers and sisters of battle is sacred to the Goddess, and Her blessing falls easily upon the comrades of a warpriest. Beginning at 13th level, you can cast a cleric spell as a bonus action, as long as all targets of that spell are allies and you have dealt damage with a weapon attack this turn. You can use this ability a number of times per long rest equal to your Wisdom modifier, and regain one expended use at the end of each short rest.

Righteous Might
Before the power of the goddess, even the mightiest of fiends and monsters can do naught but cower in fear. Beginning at 18th level, once per extended rest, you can invoke the Righteous Might of the Goddess as a bonus action. For one minute, your size increases to Large (increasing weapon damage appropriately), you gain Resistance to all damage, and your Battle Blessing can be used even on spells which target enemies. Additionally, any spell you cast is amplified by one virtual spell level while this ability is active.
