The methods of learning buff skills had been simple for Walker so far. He had been lucky to learn how to use the multi buff skill and heal skills through simple actions. The focuses on them were mostly to help others. But using elemental mana to specifically resist something was a newer endeavor.
So far, the entire party had been gaining skills to resist certain elemental manas. That was mostly because they had been in environments dense with them. The snow helped them gain resistance to water elemental mana in the form of cold resistance or ice resistance. The hot temperatures of Ignus's home had greatly helped some of them gain resistance to fire. Not to mention all of their time in the forges.
