Enemies Are Much Stronger
Starting from Act 3, regular enemies have noticeably higher stats, and you may find yourself getting KO'd unexpectedly. The Boss "Drake" also has a DPS check phase that requires high damage output to progress, so it's recommended to enhance your Heroes and Equipment before taking on Act 3.

Collect Dragon Egg Fragments
Drake takes Mannie into the Altar and destroys the key. The Altar key "Dragon Egg" has shattered into 4 fragments scattered across the Dragon's Grave, so you'll need to collect all the fragments to restore the key.
How to Craft the Altar Key "Dragon Egg"
- Open the Workbench
- Go to the Scroll Section of the Workbench
- Place the crafted "Dragon Egg" on the Altar
The Dragon's Egg can be crafted at a Workbench. The initial "Makeshift Workbench" grade is sufficient.
After opening the Workbench, you can craft the Dragon's Egg from the very bottom of the Blueprint section on the rightmost tab. It'll be instantly crafted so collect the Dragon Egg immediately.
Go near the pedestal and press the corresponding button to place the "Dragon Egg". This will unlock the Altar.
Act 3 Boss: Drake
Deplete About 25% HP
After depleting about 25% of Drake's HP, a gimmick phase begins where you must destroy the Elder Dragon Heart. You cannot progress without destroying the Dragon's Heart, so use all your Skills and unleash maximum damage output.
