War domain

The War domain was a suite of spells that were granted to clerics of war deities. The gods were those of chivalry, conquest, destruction, domination, honor, pillage, and war itself. The clerics' abilities and spells focused on battles. These abilities enhanced the combat abilities of the cleric and others. The clerics' repertoire of spells was expanded to include the ones listed below.

War Domain Spells
During the latter part of the Era of Upheaval, priests who chose this domain had access to the following spells as they advanced in level.

Other abilities were the war priest, which allowed the cleric to attack in rapid succession, divine strike, which allowed the cleric to hit harder, and avatar of battle, which made a cleric more resilient against non-magical attacks.
