Increasing Sanctuary spell level/save dc

[Groucher]

Hi
I am trying to create a human cleric focusing on buffs and am looking for ideas that would allow it to increase the DC of Sanctuary to become something a little more useable. I will be starting at level 9, in a gestalt campaign- so 9 cleric levels and undecided on everything else- I am open to suggestions, but would like to keep the main flavor cleric-y. Trying something a little different to my usual meat  shields

DMM Heighten & Persist is a go, I also saw the bard spell harmonic chorus that gives a +2 morale bonus to spell DCs that looks like kinda what I need.

Any other items/classes/feats to recommend to increase spell level or the save DC? Other than things increasing my wisdom. I am also trying to avoid spells that target the enemies will saves, but if there is anything that stands out it would be most appreciated.

Cheers!

What sources do you have available?  There might be some things in Dragon to help.  The first thing I thought of was the Sacred Performer feat but that gets complicated by gestalt.

How long will Sanctuary be up?  DMM Persist might work on this.  Or there's DMM Heighten.  Earth Spell in Races of Stone page 138 would boost the effect.

Cheers for the quick response

Oops yeah- I wrote heighten spell instead of DMM Heighten. Fixing that.

Yes to DMM Heighten & Persisting it. Earth Spell looks pretty sweet for increasing it as well.
All 3.x sources are available, including Dragon mag.
Sacred Performer looks excellent for getting more turning attempts, and a bard/cleric sounds pretty fun. It is always yay for more DMM. But yeah, the main thing I am aiming for is increasing the DC so enemies fail in hitting me/party (and waste their spells in doing so )
With a base DC of 10+1+4... just trying to see if it is worth increasing it at this level.

As always, I'd suggest Unseelie Fey (Dragon Compendium).  The winter's chill ability makes adjacent enemies take your charisma bonus as a penalty to their saves.

Yep, that winter chill ability is awesome, and exactly what I'm looking for! ...unfortunately, race is pretty much the only limited thing in the campaign, hence the human
