I like how the Defense subdomain (of the Protection domain) looks when applied to the War domain, shifting the focus so it’s a little less aggressive. I think this might be the start of a hybrid domain that would be suitable for more defensive combatants and guardians.
Let’s see how this goes.
I will be trying to create a synthesis of the Protection and War domains, using the Defense subdomain as a guide.
Granted Powers: Your faith is your greatest source of protection, and you can use that faith to defend others. In addition, you receive a +1 resistance bonus on saving throws. This bonus increases by 1 for every 5 levels you possess.
Resistant Touch (Sp): As a standard action, you can touch an ally to grant him your resistance bonus for 1 minute. When you use this ability, you lose your resistance bonus granted by the Protection domain for 1 minute. You can use this ability a number of times per day equal to 3 + your Wisdom modifier.
Aura of Protection (Su): At 8th level, you can emit a 30-foot aura of protection for a number of rounds per day equal to your cleric level. You and your allies within this aura gain a +1 deflection bonus to AC and resistance 5 against all elements (acid, cold, electricity, fire, and sonic). The deflection bonus increases by +1 for every four cleric levels you possess beyond 8th. At 14th level, the resistance against all elements increases to 10. These rounds do not need to be consecutive.
Domain Spells: 1st—sanctuary, 2nd—shield other, 3rd—protection from energy, 4th—spell immunity, 5th—spell resistance, 6th—antimagic field, 7th—repulsion, 8th—mind blank, 9th—prismatic sphere
Granted Powers: You are a crusader for your god, always ready and willing to fight to defend your faith.
Battle Rage (Sp): You can touch a creature as a standard action to give it a bonus on melee damage rolls equal to 1/2 your cleric level for 1 round (minimum +1). You can do so a number of times per day equal to 3 + your Wisdom modifier.
Weapon Master (Su): At 8th level, as a swift action, you gain the use of one combat feat for a number of rounds per day equal to your cleric level. These rounds do not need to be consecutive and you can change the feat chosen each time you use this ability. You must meet the prerequisites to use this feat.
Domain Spells: 1st—magic weapon, 2nd—spiritual weapon, 3rd—magic vestment, 4th—divine power, 5th—flame strike, 6th—blade barrier, 7th—power word blind, 8th—power word stun, 9th—power word kill
Associated Domain: Protection
Replacement Power: The following granted power replaces the resistant touch power of the Protection domain.
Deflection Aura (Su): Once each day, you can emit a 20-foot aura for a number of rounds equal to your cleric level. Allies within the aura gain a +2 deflection bonus to AC and combat maneuver defense.
Replacement Domain Spells: 1st—shield, 2nd—barkskin, 7th—deflection
As indicated above, the Defense subdomain is associated with the Protection domain. I expect the new domain will be associated with both the Protection and War domans.
