Inscryption

The Temple of the Dead is located at the bottom right and is one of the two Temples you can access at the beginning of Act II. Upon entering, you wil see the boss, Grimora, trapped behind three gravestones. You will need to piece together what happened to the three skeletons in the room and battle them in the process before you can access the boss. Along the way, open any caskets you find and any passageway that opens up for you and the well you gain access to you for card packs and epitaph pieces.

Once you have all nine epitaph pieces, you will need to line them up on the left, middle and right gravestones in order to remove them. The finished graves should read as follows:

Grimora uses more advanced Dead themed cards, such as the Bonehound, the evolving Sarcophagus (that turns into a 3 attack, 3 HP Mummy Lord) and the Banshee but none of them hit too hard. The real trick is halfway through. She will wipe out any cards you have in play and turn them into zombies all with 0 Power and 1 Health! Play these out and you will get control of your deck again. If you are in control of a good deck, this fight shouldn't be too difficult, but I found getting warmed up to the fight with the right deck took a few attempts before I got it. 

You can always jump right back into the fight if you lose, and there are plenty of packs of cards to find in both the Temple of the Dead and the Temple of the Beast if you need better options. Don't miss out on the clover next to the dock in Temple of Beasts area for a re-roll of your deck if you need it.

You may also want to take a look at Dark Offering  once you have battled the skeletons and Grimora, but you will likely need to collect a few items in order to finish off that trophy later.
