holy I used to watch your videos back in the day - the "yeeeeeo" brought me back haha. Not sure if this is purely a solo progression series, but if you're playing in Kronos & you need someone to take you to hellux/bosses lmk! I would be happy to help out :)
you should start showing your stat before you enter the boss so we can tell what you lack atleast in stat wise. As for your question with boundless rage, you should just pop all ur skill before you burst with demon bane so that all your skill cooldown should line up for each burst.
Damage skin extraction means you lose the skin, but it makes a transferable copy to give to a different character. Dance drag shop kinda mid, i wouldnt feel bad getting an android while waiting for fairy heart. Ul have more than enuff to get whatever else.
