There is a skill called "Earthquake" that adds an effect, dealing earthquake damage, which depends on the spellcasting skill.

Indeed, this adds even more confusion – I can imagine that some players might think that "Master of Earth" enhances the damage of "Earthquake." Of course, this would be somewhat strange in the sense that "Earthquake" is not available to all factions (before the expansion, it was only available to three), while "Master of Earth" is available to anyone. "This skill increases the damage of this particular spell, but only if the hero is of the correct faction and has taken that other skill from a different skill tree" :) It sounds absurd, but it is quite common in other games (usually in RPGs, though).

Fortunately, that is not the case here – "Master of Earth" is not involved. Just in case, I just rechecked it in the game using the mentor.
