AI difficulty levels

[tinkthank]

The Ai gets discounts on spells and troops as well at higher AI difficulties.

This answer is very interesting, primarily because threads like this have been up for months and months and, so far, the only canonical answer we have seen is "AI gets more (or less) points to spend during pretender creation".
But now you say that troops and spells are discounted?
Yikes!
Does that mean that (some? all? which?) spells are researched more easily? That they are cast more easily? That troops cost less gold? Less resources? Only in certain places??
Yikes ... my head is spinning!

First time I've seen that response indeed.

Hmmm. Very interesting.
