Eiro looked at the ten flaming hands that were floating around him, and then looked at the ten hands of water that were right to them. Eiro hadn't figured out enough words to create the 'Earth' version of this spell yet, but he was still able to create a water and an ice version respectively.
With a smile on his face, Eiro made the hands move around near him in different patterns. At the very least, Eiro should be able to use these to fight at least a little bit, although he would still need to test this out the next time he got the chance to hunt.
But more than that, Eiro wanted to move on and create new spells altogether. He had already basically figured out all different elemental versions of most spells that he knew of, at least if he had the vocabulary in the ancient language to do so. And that was when Eiro remembered something that Merlin said.
