Luna stared at the bamboo shoot in her hand with great concentration, carefully painting over the runes that she had drawn on in pencil and then double checked. A Runic weapon needed to be perfect, both in form and in creation, or it simply wouldn't work.
Carving the tube for her blow gun proved to be rather simple, she only had to make it smooth and pick a straight piece, since bamboo was already hollow. But after that, the Runes had to be properly placed, balancing the location against the effect of the individual runes to have them all work together.
For now, she was making the simplest of runic weapons, an enchantment that would increase the speed of the projectiles. In the runic language, her inscription was all one word, and it just had to be spread down the tube so that the dart would increase in speed as it went.
