Since I've grown fairly disgusted with Greater Sanctuary, and having a full level's worth of spells set as nothing but Heal, I started poking around for alternatives and this is what I came up with for some possible additions to the 6th level cleric spells.
Greater Glyph of Warding -- Clerics already have the lesser version, which I know I overlooked until it became sonewhat underpowered. While not looking for any extra damage for a cleric, blade barrier is slightly hazardous, and harm could cause deity/alignment issues. This spell may fill that niche up nicely.
Word of Recall -- Druids have their branch, Wizards have their tome. Not to take anything else away from the Sorcerers and Bards that have no such access to this spell, I think those, especially those who have the Travel domain could benefit from this. I don't know how hard this would be to change this from an item into a spell, and in which case it may not even be feasible and/or too unbalancing.
