Lvl 1 Earthquake Spell Observations Vs. Calculations:As you can see, what is observed in the game does not correlate with the claimed 6% damage (x4) at all. You can also notice that the observed percentage of damage taken away for each spell is not even a consistent number (1st spell appears to take away 28%, second spell takes away 26%, 3rd spell takes away a whopping 36%!, and then the 4th spell destroys the wall completely).
