Ashley: The One-Spell Mage

Ashley was born as a prodigy magic user, her magical powers were enormous and she was able to perfectly use magic from the four elements, something very rare among wizards, only the dragon Slenen was capable of such a feat. Slenen felt threatened by Ashley and therefore cast a curse on her, since then Ashley could only use a single shot of two spells and then fall exhausted to the ground. Now Ashley needs to find and defeat the terrible dragon to break his curse, and to do so she must first go through hordes of monsters until finally finding and challenging him.
