Earthquake spell math not adding up - trying to make sense of it

[Ajax]

I though the first spell was 25% ?

Only at level 4.

First spell does the stated damage qs per sopell description. Second does 1/3 of that, 3rd does 1/5, 4th does 1/7, etc.

Except on walls.

You do realize you are replying to a post from before the EQ rework update, right?

Oops. No I didn't notice that.

As far as there is such a consensus, it is that upgrading them is worthwhile eventually, but not be prioritised.

Thats kinda what I figured. I'm now more confused than ever abou them lol. Guess I will find out in 11 more days...
