Book of Demons is a Hack & Slash in which YOU decide the length of quests. Wield magic cards instead of weapons and slay the armies of darkness in the dungeons below the Old Cathedral. Save the terror-stricken Paperverse from the clutches of the Archdemon himself!

Prices
Each in the currency that store quoted — not converted: the gap between two rows is the publisher's pricing, not an exchange rate.
Availability
We put this game to every storefront we collect. A market that answered not sold has told us something about the game; a market we never asked has not, and the two are never drawn the same.

Sums Steam only; GOG, PlayStation, Xbox, Epic publish no volume signal, so the true total is higher by an unknown amount.

Un Diablo II pero con cartas
Pretty fun game.
Have only been playing this game for a couple hours worth of game time, but i gotta say, I'm really enjoying it. Managed to snag it on sale too, so double win. 9/10 would recommend.

14 of 15 markets; the rest we haven't asked for this title, not markets where it is unavailable.
14 on sale1 answered “not sold”0 we did not ask
The 1 “not sold” market is read from the Steam price pass of Sep 15: that day the store answered for this game elsewhere and gave no price there. The 14 priced markets are the same rows as the table above — each the latest price we hold, dated here when it is older than that pass. The 0 marked “not asked” were not put to this store at all — either it has no storefront there or we do not collect it yet, and neither is a statement about the game. A refusal is a refusal on one day; a store can list a title again tomorrow.

Just started the game but.. it's already hell-a-addictive. It's also very simple, engaging and easy to play! Interesting mechanics make this game even better. Highly recommended!
推薦只打一輪,因為各職業玩法其實差不多,第二輪開始變得無聊,不過以特價入手,算是符合CP值!
A nice little gem in the dungeon-crawler-corner. Very motivating, interesting graphics concept - got me hooked instantly. In most games I turn off the background music but in this one I leave it on - it's ok, it feeds the mood. This game has something unique. It starts slow but the action increases rapidly. At the moment where I write this, I have only killed the cook so far (first boss) but I have seen enough to say: it's worth it! Over 200 Achievements to get - for every achievement hunter out there... you got plenty things to do! ;-)
At first i was very skeptical, but so far i've thoroughly been enjoying the first playthrough of the game, i like the RNG system of items, and finding cards to help u along the way, it's not like a card game or anything, just ur abilities are based around cards you find, and have a certain amount of mana u can use to equip them. the enemies are plentiful and it feels like a real dungeon crawler :)
小弟可以召唤出来二弟,二弟可以召唤出来三弟,三弟死了会炸出来几个四弟,谁知道四弟是黑社会,能叫来五六七八弟,好在小弟施法可以点击取消,可是满屏的怪都在施法,点掉一个要挨一顿揍,这游戏除了你以外所有敌人施法时都是无敌的,击晕就有意思了,屏幕一转出来5个星星,挨个点击就会恢复,结果后期大屠杀模式小怪碰一下就晕,我他妈简直是好几个游戏一起玩
好玩
nie spodziewałęm się, że mi się to spodoba, ale jednak... jak lubisz diablo podobne gry - polecam zdecydowanie. Bardzo fajna mechanika gry, gra się mega przyjmnie
