Will it kill itself if Explode is used?
Yes... basically, it is a walking bomb... or maybe more of a rolling bomb since it has wheels...
Would Earthquake generate 3 shrapnel? If so, this might get a bit painful.
Yes... might need to tweak the damage output if that seems to high.
Because pillars/pendulums/towers can be destroyed 3 at once, I suggest changing non-shield to non-pillar/non-pendulum/non-tower.
I was rolling that around myself for a while, but I think it might be fine as is... at least the unupped version anyway.
The reason is that using this plus E.Q. effects requires at least 3 quanta types... 4 if you want to combo with trident...
At that point it would require some significant deck building skills to pull off a stable and competitive build.
I think the unupped is pretty safe in that respect, since it costs 6
, that means mono dark with earth mark and probably novas as well.
The upped version might be a little more feasible for E.Q. combo...
The question is, will this combo be OP enough to warrant the nerf?
