Looking to snag the EXTRA: III – Hidden Anathema achievement and unlock the mysterious Darkana Hidden Anathema? This one’s a bit more obscure than most, but once you know the trick, it’s surprisingly quick to pull off.
How to Unlock EXTRA III Hidden Anathema in Vampire Survivors Vampire Emerald Diorama Achievement
Prerequisites
Before you start, there are two important things you’ll want to have unlocked:
Gazebo: This is the character required for the achievement.
VIII – Mad Groove (Arcana): Highly recommended for speeding things up.
If you don’t have these yet, unlock them first — this achievement won’t work without Gazebo, and Mad Groove makes it significantly easier.
The Goal
The core of this achievement is tied to Gazebo’s passive stat boosts through overhealing. Each time Gazebo heals while already at full health, there’s a chance a random stat will permanently increase. Do this enough times and voilà, the achievement will pop.
Setup Instructions
Stage: Select The Coop — it’s filled with chickens running around that drop healing items.
Mode: Turn on Arcanas and Endless Mode to give yourself all the time you need.
Character: Choose Gazebo, obviously.
Arcana: From the Randomazzo, select VIII – Mad Groove right at the start. This pulls all items and pickups on the stage toward you periodically — including that precious floor chicken.
Here’s where the real trick comes in:
As you break light sources, look for the Nduja Fritta Tanto (the flame-thrower consumable).
Once you grab one, burn the chickens running around the Coop. They’ll drop a massive amount of floor chicken.
Wait for Mad Groove to activate — it’ll teleport all the chicken on the map right to your feet in a juicy pile.
Stand still and let Gazebo do their thing. You’ll start seeing stat increase notifications pop up every time you overheal.
Repeat this process: burn more chickens, wait for Mad Groove, and scoop up the food.
When to Stop
Since the stat boosts are randomized, there’s no visible cap indicator. The safest way to know you’re done is when:
You stop seeing the “stat increase” messages entirely.
Once that happens, simply exit the run — no need to die or finish a wave — and the EXTRA: III – Hidden Anathema achievement will unlock immediately, along with the Darkana Hidden Anathema (III).
