I was reading and thinking about Master_Kadish's suggestion for Fly here and thought that it might also work for something a number of people have been asking for: a short range teleport spell!
Here is the idea, in a nutshell: implement either a variation of the Teleport spell or an entirely new spell as a short-range "jump" effect akin to Leap of Faith or Abundant Step. The spell level and SP cost could be chosen to properly balance the level at which casters get this ability and the efficiency of the ability against that of a Favoured Soul or Monk.
Some possible implementations would be Phase Door, an 8th level spell, as Leap of Faith such that casters get access to the ability sooner (at level 15) but it costs much more (45 SP per use would be quite steep) or Astral Projection, a 9th level spell, which would also give the ability to clerics, make it available at the same level as to the Favoured Soul (17th) but still make it far less efficient (at 50 SP!). As a qualifier, both of these seem like inhibitive SP costs to me as a player of a 20th-level Favoured Soul, but it seems silly to make an exception to the SP-cost rule for a single spell of higher level. In addition, it would fit the flavor of Fly vs. Wings, with the caster being much less efficient but able to use the ability sooner while it is essentially a free, inherent benefit of being a favored soul. With this in mind, my personal preference would be for this to be added as an option for the regular "Teleport" spell, coming in at 30 SP and a much longer cooldown to balance out the fact that it is made available earlier.
