Grimestone tapped his device once more, displaying an image of a slate with the glowing word 'shield' engraved on it.
"For example, simply engraving 'shield' doesn't require that much will, and the resulting shield's power will depend on the amount of mana you can infuse into it."
He tapped his device again, and a slate with the glowing words 'impenetrable shield' engraved on it appeared.
"However, engraving 'impenetrable shield' would obviously demand more willpower to create. But keep in mind that merely engraving 'impenetrable shield' doesn't guarantee an invincible shield; its strength is directly proportional to the strength of your will."
"This example applies to shields, but rune engraving follows the same principle overall. The stronger your will, the more powerful the rune. Now, our first lesson today will be about harnessing your will."
