By completing early King Darion quests, you will soon get access to certain units in unlimited numbers, like Archers and Swordsmen. That will help alot in your future battles, knowing that you don't have to exrtra worry about losing them. Just come back and restock. In the Isands, you will be able to buy new units like pirates, marauders and sea dogs. Sea dogs are particularly vicious, with their special attack which can damage all neighbouring units. Griffins are great for their unlimited retaliation ability, put stone skin and bless on them, and watch them rock!
All in all, try to learn your units and their weaknesses/strengths/special skills. It is the meat of the game..Same for your spells. There are some really killer spells/critters combos out there
