Tactics for playing as the Sylvan faction.

To be honest, I was shocked when 24 Druids raised a hero's magic skill from 9 to 37. With some simple calculations, it becomes clear that the hero gained 28 magic points. However, this is not the limit. The same 24 Druids gave another hero 16 magic points, but without the Sar-Issa set. In other words, in the first described case, only the hero's knowledge was a limiting factor. What can I say, dear Sylvan elves... Collect the Sar-Issa set :) 2 items, and incredible magic is guaranteed :)
