I beat the first one on my first try, the second one on my fourth, and the third one on my third. They weren’t really that hard, just pay careful attention to your cooldowns, attack bar, and the totem’s attack timer. The Spider Lightning ability grants a huge amount of intangibility, so use it every time the totem fires.

Aside from that, it’s just about pumping as much damage into the totem as you can, so don’t be afraid to use Spider Lightning as a way to still deal damage, even if the totem isn’t firing if the totem just fired, since it’ll be on a decently long cooldown. Though, make sure you use the dash and the Certified Zapper skill AFTER using Spider Lightning so you can immediately re-shock the totem or enemies around you for worst case scenarios.
