Yes, like 2 mins or something like that. If you get a right nuke, a T5 will deal like, waht, 90% damage or something like that.
But T5 can be mp intensive. Use too many and u're out of MP, and since u're perma kiting u don't have many ways to recover MP (vile elixir maybe?).
There's a lot of luck involved becaose of the random Horde Lullaby too, fucking your shadows and letting you get hit (and those hits DO HURT trust me)
It took me 4 or 5 attempts.
Comparatively, I did the RUN one on second (could say 1st technically)
Either way, glad you did it
