Eden now plays with GMS numbers. Your damage, monster HP and boss HP are the values you know from GMS, so guides and gear checks work the same here.
- Gauntlet Hero is gone. The permanent +100% Final Damage buff no longer exists, so your numbers are the real GMS ones.
- Monster HP is no longer doubled. Monsters have their normal HP again.
- Bosses take full damage. They used to ignore 30% of every hit.
- Damien, Lucid and Arkarium have their GMS HP. They had far more than GMS: Normal Damien is now 1.2 trillion (it had about 23 trillion), Hard Damien 36 trillion, Lucid 24 trillion, and Arkarium 2.1 billion (Easy) or 12.6 billion (Normal).
The Damage & boss HP page lists the HP of the big bosses.
