1. Logistics
2. Defense
3. Tactics
Everything is clear here...

And here, I might be misunderstanding, please correct me:
4. Pathfinding, again, depending on the situation, if there are few roads on the map.
5. Ranged attacks... for these lizards or a combined army?
6. Water, I assume, is for healing, mass weakness, blessing, prayer, teleport, and counterattack?
7. Earth is for stone skin and teleport.
8. Air... acceleration?

I would replace 4 or 5 with wisdom... and what about magic resistance and intelligence, ballistics? :)
