Easy "All unlocked!" Achieveme...
	Various Steam Achievements...

It looks like the description for this achievement is wrong because it unlocked when I used hundred spells ( in-game bonus quest IV for casting hundred spells, that unlock all spells and four slots to use your spells later). So it shouldn't be "All achievements unlocked" but "All spells unlocked" instead.

Complete the indicated task to unlock the achievement.
