However, keep in mind the difficulty for Special Dungeons is not entirely relative to the difficulty of Normal Dungeons. <br>
(Typically for the Event Dungeons, they are much harder compared to the difficulty required to unlock them.)
*Not every Event Dungeon is the same; some are much easier to deal with than others (often due to Boss Mechanics).
*The first three difficulties are relatively Easy to beat. You shouldn't have much trouble beating them.
*From Demon difficulty, it gets a bit harder as the enemies start to gain more Attack and HP. You'll need to start having a well-rounded Deck.
*There's a significant gap between Dragon and God difficulty. The Bosses are significantly harder from God difficulty onwards, and you'll need a fully-powered up Deck to stand up to them!
*True Dragon King is currently the hardest Difficulty. It typically offers beefed-up Bosses often with altered mechanics. Sometimes, you'll have to face several Bosses in a row (or together)!
