This is a build iLights showed me. It's more for personal use so I dont forget it but it might be of use to someone else.
Hint 3 : Place temporary buff beam so drain aura reaches the other buff beam where tower stack is.
Hint 4 : Make ensnare smaller 3 times.
Hint 5: Make ensnare smaller 1 time.
1TB and 2IB (1IB is enough to get through it but 2 makes it faster)
