Paladin - How do my blessings work?

Blessings are a type of short-duration spell that you can cast on yourself or your allies to grant combat bonuses or other special effects. Blessings are cast instantly, last for five minutes. There are a wide variety of available blessings, but each character can only be under the effect of one blessing per paladin in the party. Part of the strategy of playing a paladin is figuring out which blessings are the most useful for different classes and determining in which situations each one is most appropriate.
