Protection from Earth Bless and Protection-Based Alteration-School Earth Buffs

[Immaculate]

So the basalt king, who is armed with only a quarterstaff and no armor but has protection of 16 does not benefit from the protection effect of the earth bless?

But he does benefit from the ironskin/stoneskin spells and from the reinvigoration from the earth bless?

BUT if i put armour on him, he would get the armour benefit and the earth bless (protection) effect?

Thanks for all your clarifications....
