For the relation to my question
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.
If I take the "Defense Subdomain", do I still keep the +1 Resistance bonus on saving throws?
The resistance bonus is from the domain itself, not the spell-like ability from first level.
