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!

액트가 3개 있습니다. 액트1은 꽤 지루했어요. 그리고 액트1 보스에서 첫 전설카드 주는데, 내가 사용하는 카드가 나와야 여기서부터 잼있어집니다. 액트2 중반부터 마법카드들도 모이고 적응도 되면서 게임이 조금씩 수월해져요. 액트2 보스에서도 전설카드 주는데, 운이 좋으면 그 전에 전설카드 한 장 더 모을 수 있습니다. 디아 + 덱조합 게임이지만, 말이 덱이지 모은 카드들이 스킬, 아이템, 패시브역할 다 합니다. 개인적으로 상상하던 방식하고는 거리가 좀 있었지만, 패시브랑 스킬 카드 조합의 묘미가 있는듯합니다. 생각보다 섬세한 게임입니다. 특수스킬 아니면 한마리한마리 지정하면서 공격해야하고, 디아처럼 몹몰이가 가능하긴한데, 몹 주변 보호막을 하나씩 깨줘야한다던지, 몹 분노게이지도 신경써야하고, 몹 캐스팅 방해해야하고, 등등 신경쓸 부분이 은근 많습니다. 디아처럼 화끈한 플레이를 기대하다가는 초반에 게임 접을 수 있습니다. 이 게임만의 색깔이 있으니, 우선 아닥하고 액트 2까지 깨보시길 추천드립니다. 그리고 전사 추천합니다. 잘 안 죽어요. 가이드 없이 액트3까지 한번도 안 죽었습니다. 법사는 너무 잘 죽으니, 게임에 적응하시고나서 하시길 추천합니다.
La verdad es que el juego es entretenido.

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.

Its a great and fun game. It got me really fast.
jeu sympa
I love this game. Its just perfect to pick up, play for a bit and come back to after a while.
I wasn't sure if i'd like "diablo on rails", but it's actually pretty fun! Furthermore, I don't tend to like deckbuilding games much, but for this game, "deckbuilding" just means that you find your skills/passives/potions in the dungeon instead of innately or from a trainer. The fact that they come in card form is just an aesthetic decision, really. The graphics are pretty, the game mechanics are enjoyable, and the game has a good sense of humor. It gave me a sensible chuckle several times, especially the skeleton in the lava. I can see how some people might find it difficult, but I cruised through normal mode without dying. A lot of the bosses are more of an exercise in patience than a challenge, mostly because enemies are invincible while they're casting a skill, and some enemies/bosses cast skills a LOT. They had a good idea with boss AI, though, where each boss has visible "stages", where you have to figure out what to do to progress to the next stage by the icon that shows up in the boss progression indicator. Nice touch! There's a decent amount of replayability, and you can keep playing with your character once you finish the story, which is always nice. There's only 3 classes, though. I would've liked to have seen more, but if you're an achievement hunter or just want to grind out all the cards or try out roguelike mode, you might end up playing it for a good long while.
디아1 잘 배꼇음 하지만 손가락이 아프다
Fantastic roguelike that respects player time in multiple ways. Wonderful game right from the getgo! The fact that it has a feature to establish expected session length is such a huge blessing for me. I have no shortage of games to play, but when playing a game (and [i]especially[/i] when starting up a game for the first time), you often have no idea how much of a time investment you'll be expected to put in these days. And it isn't that I only want short experiences, but a game that's solid and enjoyable while still possible to play in bite-size pieces is really valuable for those times when I can't be sure I'll have four or five hours to potentially work my way through the opening of a game. Really glad I took the chance on this one.
i love love love this game !!! finished it while it was on game pass and now i bought it to play even more.... it's so good
