Well, the Heroes' Feast bit is dependent on the number of clerics able to cast it.

The same thing applies to most of the others. How many clerics and mages are there? One out of ten, a hundred, a thousand, a million? Any number will change things, but how MUCH they change things, and in what way, will depend greatly on how many there are.

The teleportation thing? Anyone able to do "Adaption" and Teleport can get to the moon in a very few steps. As in, if you're a reasonably high level mage you can get there with no problem.
