HARD MODE BOSS: Electro Worm | Mage (Solo / No Damage / Efficient) - Portal Knights

Looking back at my first time fighting Electro Worm with Mage, I was woefully under-equipped and my strategy wasn't top-notch. Here I've made those improvements, cutting the time about in half despite having a few bad cycles where I could not get close to use Greater Poison Rain, which cut down on the amount of crits I was landing to recharge my Masterwork Lightning.

Regardless, here's the setup:

+87 Int
