Harmony - Troop Symmetry

First, answer the question: What is a guardian angel in religion, not in a fictional world?
Similarly, in Ashan, people who worship Elrath receive his patronage and blessing, which is expressed, among other things, in the fact that his angels, sent by him, help people in battle in one way or another.
With this, we close the discussion about the logic of this skill, and I would still like to find out what specifically can be done with it to make it more like a Special Ability (currently it is too weak for a Special Ability).

Regarding machinery, within the context of Ashan, machinery is more suitable for non-religious people, as well as for creators of constructs, engineers, and scientists (that is, primarily mages and dwarves). For humans, leadership and light magic should be the primary skills, and the third skill should be either a "defense" skill or an "attack" skill.
