Chaav's Laugh - Choice of Alignment

[Ser Shroom]

Hello

Chaav's Laugh currently functions as follows:-

Chaav's Laugh
Enchantment
Level: Cleric 5
Components: V
Casting Time: 1 standard action
Range: 40ft
Area: 40-ft-radius spread centred on you
Duration: 1 minute/level
Saving Throw: Will negates
Spell Resistance: Yes

You release a joyous, boisterous laugh that strengthens the resolve of good creatures and weakens the resolve of evil creatures.
Good creatures within the spell's area gain the following benefits for the duration of the spell: a +2 morale bonus on attack rolls and saves against fear effects. plus temporary hit points equal to 1d8 + caster level(to a maximum of 1d8 +20 at level 20).
Evil creatures within the spell's area that fail a Will save will take a -2 morale penalty on attack rolls and saves against fear effects for the duration of the spell.
Creatures must be able to hear the laugh to be affected by the spell. Creatures that are neither good nor evil are unaffected by Chaav's Laugh.

A great cleric spell however it currently only really has utility for good aligned clerics. I would suggest that Chaav's Laugh function like Protection from Alignment - with four options ranging from Good, Evil, Law and Chaos - applying bonuses to the alignment chosen and penalties to its opposite.

It might be interesting if who it affected and how was based on the alignment of the caster similar to Hammer of the Gods rather than full freedom to pick an effect.
