Earthshatter Question

[Xenofaul]

With the Earth Toss Shard, it says its damage radius is increased by 260 or something like that. Does that mean it no longer is solely a single target tower, but instead has a very small AoE radius?

Also along the same lines, does anyone know how the ShatterQuake modification works? The tooltip is extremely vague.

correct, it makes the tower a relatively small aoe but large ranger tower. the knockup limits how much actual "aoe" it does, but since its so strong many weaker enemy types wont live through the first hit anyway.

shatterquake basically does 1 earthshatter hit, and then after about half a second, a small ground based aoe where the first hit landed to anything on the ground there.
Both together make it a relatively strong aoe tower that hits ground only
