Secondary skills in Heroes 3.

Regarding the Companion, everything is more or less clear: Wisdom, Earth, Air – on L and XL maps, logistics are key (it works well on other maps too). As for the Human, no matter how much I play, I keep realizing that it all depends on the map and the specific opponent. Well, Wisdom, of course. And Earth, probably. Although sometimes, I had to take the Sphere of Inhibition to defeat an overpowered Solmyr with just skeletons. And magic didn't help at all. With the Human, mobility is what matters. That is, Town Portal and Logistics. It's good if there's a Dimension Door or flight on the map.
