As you gain levels, you gain experience. With this experience, you grow stronger and stronger! You will see and realise, the creatures you have from when you first started practising magic, won't grow with you. You will become too strong. Or rather, your initial pixie or griffin will become too weak to attack with it. But do not fear! A higher tier creature, a creature with a higher uselevel will become available for you, to attack with or to defend your castle with.The next thing you will witness when you grow stronger and more experienced: you will have to prove your power. At certain magic skill levels, attacking creatures will put you to a test: a skill challenge. These creatures are incredibly strong and cannot be killed by creatures from the same race! This means you must invest your skill points in 2 different skills! This means a diabolic mage will also have to invest in for example elemental skill, to be able to use elemental creatures, just to pass the diabolic challenge.Be aware, because these challenges will make you think about your skill points you have left to spend. Your skill points are needed for your main skill and your secondary skill.
