For the current format, see Dark Tower.
Dark Tower unlocks at League 20 and it allows you to run mini tournaments against other players to test the overall strength of your collection. After paying a fee, which depends on your maximum league level, you play several battles against the AI until you reach 7 wins or 3 losses.[1] The starting player is randomly assigned for each match.
Once you reach seven wins or three losses, you get chests depending on how many wins you managed to achieve. The number of cards in the chests depends on your current league level.
- ↑ For mobile players, the maximum number of wins is 5. See the Clients#Mobile app for some other ways the game differs in its PC and mobile versions. For the remainder of this article, it will be assumed you are playing the PC version of the game.
Squad
During fights in Dark Tower you use all your cards. Each turn you are given a choice from four cards of the same rarity that have been randomly selected from your whole collection. Then your opponent gets to choose a card of the same rarity from his collection. Next turn all your cards are discarded and you must choose from a new set of four cards. For each turn, regardless of who goes first, both players get the same rarity cards to select from.
Unlike the Pit, you can use the same card more than once in a single Dark Tower battle, so there is no penalty for using the best card you have available.
If you don't own at least four cards of a given rarity, the missing spots will be filled by cards of some other rarity.
Matchmaking
The opponents one may face are determined by player's total army power (aka total collection might), which can intuitively be seen as the sum of the mights of all cards one owns, without contributions from pets, reborn and soulbind. Therefore, troops isn't necessarily a good gauge for comparing opponents.
Matches are arranged so that every opponent is picked from a pool of players having an army power equal or lower to player's own - but not superior. In addition, the following coefficients are applied:
| Total might multipliers | |
|---|---|
| Match | Multiplier |
| 1 | 0 |
| 2 | 0 |
| 3 | 0 |
| 4 | +5% |
| 5 | +10% |
| 6 | +20% |
| 7 | +30% |
essentially meaning that the further one digs into the quest, the harder their opponents. Note that - as mentioned above - pets aren't taken into account, so whether a player will meet players with pets or not is purely up to luck. Likewise, matchmaking isn't affected by win/loss ratio.
Example: a player has 300k army power and 400k troops. He won the first four matches, and the 5th opponent is drawn from a pool ranging from 0 and 330k army power (not 440k troops!). Said player may or may not have a pet, and in such a case said pet may range from lv1 to lv26.
Note that some players may experience a peculiar troops/might ratio, that makes it so they will face the same opponents each time they restart DT. This is simply due to the fact that the pool of possible opponents is very narrow.
Difficulty level
The opponents you are matched with depends on your total collection might (see above), but the pattern of card rarity depends on your current league. If you find Dark Tower too hard, you can drop to a lower league or move up to a higher league, depending on whether your collection has more highly leveled commons and rares or more highly leveled epics and legendaries.
Using the table of rarity patterns below can help you figure out what league is your ideal spot for Dark Tower wins. If your best cards are able to appear early on, you stand a better chance of winning a match.
Rarity pattern
Each turn you are given four cards of the same rarity, and your AI opponent will also play a card from that rarity. What that rarity is depends on your current league and what turn it is. In the table below, C = Common, R = Rare, E = Epic, L = Legendary.
