Ed sighed internally before taking an upright posture. It was time to teach Zephyr a thing or two.
'Zephyr, after you've gathered the mana inside of yourself, try to send it outwards. It will create a gust of wind' Ed transmitted the next step. If Zephyr had critical thinking skills, it might have been able to do this without Ed's instruction.
There was another problem that Ed failed to mention much earlier. These skeletons couldn't chant. This meant that they could only manipulate the elements around them, their situation was hopeless in this regard.
Zephyr nodded and out of his glowing bones, came out a soft wind. A zephyr.
If Ed could feel things he would think it quite pleasant but since he couldn't, he was slightly disappointed.
