Lake fairies holy cow!

[Keneth]

Fairies combined with Anga's Ruby and bonus damage items like Isshara's Whip are likely the most damaging unit in the game due to their sheer numbers. Their only drawback is low stats, since they have low defense and low hp they can get pounded quite hard when in harm's way but with careful use of timeback and resurrection, it shouldn't be too hard to keep them alive. Also, elves and dwarves don't like each other, they'll both get a morale penalty if you include cannoneers.
