With the magical staff, any non-elemental can wield elemental powers as long as they hold the weapon. The staff acts as a converter and any energy that passes through it would be changed into the element of the orb embedded into it.
On the same note, Jonard's little experiment paved a new road to material embedding. Power stones and speed stones could now be used to further enhance any equipment as long as it was able to take the brunt of the embedding process. Some of the equipment used to embed mid and high-tier stones was destroyed due to overload.
Everyone was reminded of an important rule of crafting that day, high quality materials need high-quality equipment. It would be impossible to enhance a low-quality item using high-quality materials since its durability wouldn't be able to last the whole embedding process.
