- Tactics skill in Heroes 3.

First Aid, which doesn't even restore creatures.

What do you mean? :eek: It allows you to control the infirmary, restoring up to 100 HP per round for a specific stack on the expert level. If every high-level unit counts, and the hero can't resurrect – it's a useful skill, although quite secondary.
You'll say next that "Elixir of Life is useless"... :)
