Paladins and mind affecting spells like bless

[Uleaum]

Paladins eventually get imnunities to compulsion and charm spells. Does this mean that spells like bless and heroism cease to work on them, or can the paladin trick himself into being convinced the bless or heroism spell works on him (i.e. allow himself to be susceptible)?

[Avianfoo]

Immunity means the paladin is immune to those effects. Luckily the paladin only becomes immune to your beneficial bless and heroism spells (compulsion) at level 17 when there are much better options available.
