Alter Aeon FAQ (Frequently Asked Questions)
FAQ 10.3 - Why isn't fly the way I think it should be?
Because 'fly' isn't really fly, it's more like 'levitate'.
Fly really should be named 'levitate 6 feet', where it will lift
a character up to 6 feet off the ground but no higher. Thus fly
might be of help when climbing walls, but casting fly would not
be enough to eliminate the need for the climbing skill.
A lot of things in were created as though this were the intended
behavior, but not all - for example in an airfall room, you should
still fall if you are flying, but not take damage when you hit the
ground. You also shouldnt fall as fast.
Not everything about the 'fly' spell is up to our satisfaction, so
don't be surprised if it changes slightly in the future.
