The final wing has arrived! With it comes four new bosses that you're going to need to take down and these ones won't go down without a fight.

Hall of Explorers Heroic Guide

Rafaam has stolen the Staff of Origination! He's using it to animate various exhibits around the museum in an attempt to stop you. We must first get through them before we can finally wage battle and end this conflict for good.

Skelesaurus Hex Heroic

This former T-Rex sports 15 armor and 30 health which gives him a free Unstable Portal in the form of his hero power, Ancient Power. This of course means that even if you play the match to a T, you'll need RNG to be in your favor. That is unless you want to end up like us who have to deal with these shenanigans.

Rafaam Unleashed Heroic

The real Rafaam takes some luck as you hope you both draw good cards from Rummage and that he has no luck pulling the best bosses. However, stealing one of those goes a long way towards helping you win, so that should be a goal.
