Wo Long contains 70 Wizardry Spells. They are mystic techniques that can cast powerful elemental spells or buff you in battles. Wizardry Spells consume Spirit and require specific Morale Ranks to cast.
As you play through the story, you will earn Wizardry Points that you can spend to unlock new Spells. To do so, head over to any Battle Flag and choose the Wizardry Spells menu, then Learn Wizardry Spells. To unlock this achievement you need to learn all Spells for all Five Phases, Wood, Fire, Earth, Metal, and Water. On your way to level 80, you will get enough Wizardry Points to unlock them all, so don’t even worry about this achievement. It should also be pointed out that for this achievement unlocking the Spell is enough. A Spell’s required Virtue level isn’t needed.
