Paladin's used to have an Ability for this "Succor" it had another name infront of Succor, honestly cant remember it, it healed a decent chunk (at lvl 50 in 1.0 it healed about 1400 HP) it had the additional effect of if the PLD cured someone else, it cured the PLD for half that much, so 1400 to another player, healed 700 to the PLD, it was a unique Cure spell for PLDs, that had a nice Emnity tool to it, due to healing other's, it did cost quite a bit of Magic too, so it wasn't something you could spam.
