Ghoulish Gallery is where you acquire Collections to equip your heroes. You can unlock Ghoulish Gallery after reaching Chapter 6. The Collections can replace heroes’ original Artifacts and be used in most battle environments, including Cursed Realm, Nightmare Corridor, and Treasure Scramble.
Each Collection has its own unique effects and can be enhanced with Abilities. You have 7 chances weekly to enter and explore the Gallery. In each exploration, you can choose the Collections you desire, and upgrade and enhance them while exploring. Weekly exploration chances will not carried over to the next week.
Collections
Collections are essentially a new type of artifacts. Initially, 10 Collections have been added to the game, 2 for each class.
The number of identical Collections you can have and use is unlimited, but the player can only make 7 Collections per week. The collection takes up the Artifact slot on heroes page.
If you remove a Collection, the slot will have a cooldown of 24 hours until you can use the next one. To put it on earlier, you will need to pay 100 diamonds. You can also recycle an unwanted Collection and get 100 diamonds for it.
To unlock Skill Level 1 of a Collection, you must get a Skill Level ability during your Gallery exploration and add it to your Collection when your run ends. To unlock Skill Level 2 of a Collection, you must use Miracle Worker totem before starting a new Gallery exploration and you must get two Skill Level abilities during your Gallery exploration and add them to your Collection when your run ends.

Exploring the Gallery
Each time you enter the Gallery, you can spend up to 3 Bizarre Totems to increase your exploration gains, which will grant you more powerful Collections at the end of the exploration.
You start exploring the Gallery with three random heroes at Elite ascension. You will be able to recruit new heroes in the Gallery and upgrade the heroes available in the current exploration by progressing through the floors. Your acquired heroes cannot be taken out of the Gallery after an exploration. You will also be able to select Unions to strengthen your exploration team.
There are a total of 10 floors in the Gallery. After exploring all floors, you will receive the desired Collection. While exploring, a battle failure reduces your Invisibility. When your Invisibility comes to 0, your exploration ends early.
You can obtain Abilities by defeating enemies in battles. Abilities can enhance Collections after the exploration.
Besides battles against enemies, here are some other things you can find during your exploration:
– Recruitment: Choose one of the three heroes available.
– Select union: Choose one of the three unions available.
– Safe: win a random Ability.
– Trap: You lose or gain invisibility.
There are also 5 types of rituals you can see in your exploration:
– Combination Ritual: Combine three abilities of the same tier into a higher-tier ability. The newly combined ability will randomly inherit the type of one among the abilities used.
– Refresh Ritual: Select 1 ability. Retain its Ascension Tier. Refresh its type.
– Replicating Ritual: Select an ability to replicate and receive an additional low-tier replica of the ability.
– Swapping Ritual: Select two abilities to swap their tiers.
– Upgrade Ritual: Increase the tier of one ability, and its effects will change randomly.

Etching Abilities
After each exploration, you can etch your collection and enhance them through abilities. Each collection has 3 Attack Slots, 3 Defense Slots, and 1 Common Slot. The Slots are unlocked depending on the collection’s level. You can etch Attack abilities on Attack Slots, Defense abilities on Defense slots, and any abilities on Common Slots.
After being etched, a collection cannot be changed or enhanced by any other means.
List of attack abilities
Top-tier offensive abilities
– ATK: great stat for most heroes, except on heroes where their damage is mostly based on their HP instead of ATK, like Awakened Shemira.
– Full ATK: great offensive stat for heroes whose damage is not important, so this stat is good for giving an attack buff to your teammates.
– IS (Insight): it is one of the best offensive stat for heroes with CC skills because it increases your chances of making CC work against heroes with high Tenacity. It is useless for heroes without CC skills.
– MP (Magical Pierce): it is a top-tier offensive stat for 
Intelligence heroes. It is useless for non-Intelligence heroes.
– PP (Physical Pierce): it is a top-tier offensive stat for 
Agility and 
Strenght heroes.It is useless for Intelligence heroes.
Mid-tier offensive abilities
– CRIT: it is great to increase your chances of hitting critical damage.
– CDA (Crit Damage Amplification): amazing for heroes that already has a high crit chance (e.g. most Intelligence heroes).
– ERR (Energy Recovery Rate): improve your overall energy gain from different sources, so it is a great stat for most heroes. Especially for heroes that really depends on ulting as fast as possible to be useful (e.g. most mages).
– Erosion: it is useful only for heroes that has a damage over time skill or other skills that contain the term “health loss”. Awakened Belinda, Liberta and Maetria are the best heroes that benefit from this stat. But it is an useless stat for most heroes.
– PRF (Proficiency): it is a great stat for heroes with CC skills and/or debuff skills because it increases their duration. Once an ennemy has a mark above his head he is considered debuffed. This stat is useless for heroes without CC or debuff skills.
Low-tier offensive abilities
– Full Erosion: most heroes do not benefit from Erosion. So a Full Erosion stat will be weak in most scenarios. This ability is great for Lorsan and Awakened Safiya though.
– 
LL (Life Leech): it can be useful for some Warriors damage dealers, just okay for other damage dealers with good normal attack, and awful for all other heroes.
List of defense abilities
Top-tier offensive abilities
– DMG Resist: it is the best damage reduction stat. Always choose this.
– DEF: it is a top-tier defensive stat for Awakened Brutus and Lucilla, but not that great for all other heroes because it is less strong than DMG Resist, CBR and CDR.
– Full DEF: good defensive stat, especially on heroes that do not need that much defense like Alna and Canisa & Ruke.
Mid-tier offensive abilities
– HP: good defensive stat, but it is slightly worse than DEF.
– Full HP: another good defensive stat, but it is slight worse than Full DEF.
– TY (Tenacity): it is the best counter to heroes with CC skills. The higher your Tenacity, the greater your chance of resisting CC. Good defensive stat for all heroes.
– DISS (Dissolve): another amazing counter to heroes with CC skills (and heroes with debuff skills). It makes enemies’ CC/Debuff last shorter. Good defensive stat, but it is less relevant than Tenacity.
– CDR (Crit Damage Resistance): the higher your CDR, the less damage you will receive from critical attacks. Good defensive stat for all heroes.
– 
CBR (Crit Block Rate): it increases your chance to block crit damage. Good defensive stat for all heroes.
Low-tier offensive abilities
– Armor: improve generated shields from the hero. For most heroes, it is much better to improve any other defensive stat instead of Armor. Ivan and Astar are some exceptions of heroes that benefit a lot from Armor.
– HEAL: improve healing output. But just like Armor, it is better to improve those other defensive stats mentioned above. Awakened Solise and Talene are some exceptions of heroes that benefit a lot from HEAL.
– 
Buffer: it is useful only if your facing heroes that has a damage over time skill or other skills that contain the term “health loss”. So it is an useless defensive stat against most heroes.
– 
Full Buffer: just like Buffer, but even worse because it gives very small stats to all heroes instead of big stats for a single hero.
Special ability (you can etch this ability only on common slot)
– 
Skill Level: The skill level of collections ascends 1 level.
Skill Level is undoubtedly the best ability, because you must have the Skill Level ability to unlock Skill Level 1 of your Collection Artifact. And you must have two Skill Level abilities to unlock the Skill Level 2 of your Collection Artifact. But you can only equip two Skill Level abilities if you have used Miracle Worker totem. Miracle Worker and Supreme Skillset totems also increases your chances of getting a Skill Level ability during your run. Farewell Gift gives a guaranteed Skill Level ability at the end of your run.
The other abilities you should choose will vastly depend on its rarity and on which hero you will use your Collection artifact. For example, MP (Magical Pierce) is useless on heroes that do not deal magical damage. IS (Insight) is useless on heroes that do not have any control skills. See the tier list above for more info.
