A primitive culture living on the world of Ori-Alona has developed a system of magic based around dreams and the harnessing of elemental spirits. While there is no real basis for this magic and it's almost completely useless in effect, what kind of tricks could be used to give the sense of efficacy in the following:
- magical healing
- turning the tide of battle
- (some) control of weather
- taming animals
For example, some sort of chemical fog could create a sleepy, dream-like state in those nearby which could help heal some ailments. Although not "magical" in reality, it could appear to be.
A crystal could light up/heat up when shaken vigorously. Put some of this into a staff with a grass-woven bulb at the end and watch it create "eerie green light" that will summon a rainstorm. Like this.
The effect of this magic to convince those around it that it is actually doing something should be extremely subtle, giving you an odd chilly feeling and causing you to notice what are actually just complete coincidences or basic chemistry/psychology.
So how do I do this? What kind of rituals, chants, and materials could give a sense of something actually happening that is beyond the ordinary when really nothing amazing is happening at all?
EDIT: I found a great answer to this somewhere else that I should be able to adapt to the inverse situation:
