Magic Deer

Overview
They may look impressive at first glance when you fight them, but they're not actually all that great. They have high base Strength (5) and low Magic (1) stats, but their growths are reversed with low Strength Growth (0.7) and high Magic Growth (1.5). If you end up getting any you're better off selling them at the market, where they fetch a high price.

Combat
They can be acquired early game for fast access to powerful healing spells. Even after they outgrow their usefulness, you'll want to keep an eye out for them so that you can defeat them for the useful LightShards they drop.

Moneymaking

 * They're the 2nd best creature to sell. They can be sold for 500 gold at Medium size and for 1500 gold at Enormous size. Every level above 1 additionally increases their price by 5%.
