Since my I created my new player Kagrenac, my ultimate goal is to retrieve every Dwarven artifact possible and clear out all the Dwemer ruins. I went into a warehouse next to Mzulft to test my fighting against the Dwarven Constructs. Only thing to be found there were spiders, and damn those things have a lot of health; melee wasn't enough. So I want to raise my destruction but is better for taking out these machines? Fire or Spark?
Thanks in advance 

I'll probably have him die on top of a mountain near a Dwemer Ruin like http://static3.wikia.nocookie.net/__cb20130210003859/elderscrolls/images/3/37/Fahlbtharz.png
