Thanks and Lancer can only make spears and only of that particular shape, however she can use them for other purposes and adjust the length of the pole. A common thing she’ll do is use them to help with gymnastic fighting techniques (pole vaulting, using them for a spinning kick, etc.). She also can use them to do things like climb buildings by using the spears as climbing picks.
Here is a contest entry, a white mage. In this world, there are several magical orders, each order signified by a color. The black order represents darkness and death, the red order represents fire and anger, and so on. The white order represents life and light and is in a constant struggle with those of the black cloth. This is a standard white mage, an adept with light spells such as the orb of blinding light he is creating here.
