order strings...

so i need to know how order strings infulence an ability, let's say for example's sake only i wanted to make a devotion aura that i would use manually and then it would give say 5 armour for 5 seconds, can i do that with order strings? and let's say i have two abilities based off the same thing, can i use order strings to make it so they don't activate together and have a shared cool down?

I beleive that:
1. Order strings are used for triggers to order an unit to cast an ability.
2. Changing order strings has NO EFFECT WHATSOEVER on the order used.

also 2 spells with the same order string (most likelly based on the same ability) will overlap in game causing bugs.

You can't make a passive ability into active without triggers. But you can always use innerfire for this stuff?

it was just an example i need large amounts of spells where they are cast once clicked like war stomp, but i need them not interfere with others...
