Paizo has done a good job playtesting stuff mostly so far but there are some balance offenders lurking out there, I'm making this thread to get a discussion going and alert people that these spells are not balanced and can cause problems
if you know of other examples like these post em up
1. Euphoric Tranquility - http://www.d20pfsrd.com/magic/all-spells/e/euphoric-tranquility
So, no save and they can't attack or cast spells for at least 16 rounds, AND they are helpful, so diplomacy is outdated. This one is pretty high level but it's straight up broken, touch required or not...there are a lot opponents at high level which are not hard to touch.
2. Litany of righteousness - http://www.d20pfsrd.com/magic/all-spells/l/litany-of-righteousness
Hey paladins weren't powerful enough smiting evil already, amirite? Swift action no save...didn't the designers learn from 3.5 leap attack etc? Giving stackable damage multipliers is a bad idea. You can make a 20th level paladin archer with this spell deal well over 1000 damage with a single full attack.
Cold Ice Strike - http://www.d20pfsrd.com/magic/all-spells/c/cold-ice-strike
This was apparently nerfed from a 60 foot cone to a 30 foot line but that doesn't really address the problem, dealing 15d6 cold damage in an area at range with a swift action with a 6th level slot is a bit imbalanced if not outright broken. Also, this doesn't fit the general cleric list at all. Compare it to a quickened lightning bolt, that requires another feat and takes a 7th level slot...
3. Litany of Vengeance - http://www.d20pfsrd.com/magic/all-spells/l/litany-of-vengeance
So, +5 damage for everyone that hits, swift action, again no save. That's bad enough, but the duration is "instantaneous", by RAW then, the target takes +5 damage....forever? So as a DM, I hit a pc with this, they take +5 damage on every attack that hits them for the duration of the campaign?
