ThaliaPortrait Small You got the Evo! Remember, you can use them to Ascend your Heroes! This is a good thing, you want to do that!

Evos are creatures that can be found in Dungeons, obtained from chests (Treasure Rooms), or obtained from Portal summons.

If an Evo is encountered in a dungeon, it must be hit at least one time during the first round of the battle to collect it. All Evos are Level 1 and defeated (collected) after one successful hit, regardless of their rarity. If an Evo does not take any damage by the end of the first round, it will leave the battlefield.

Evos are used to ascend your Heroes to unlock new Abilities and Traits abilities and traits, and all heroes can undergo two ascensions. Evos come in many different forms and colors, and there are multiple stages for each type of Evo. Evos can be classified by Element and class. The four classes of Evos are Larva, Sprite, Monarch, and Celestial. Below is a list of all the currently known Evos.

Evo Larvae

Small, unhatched, common type.

Evo Sprites

Medium sized, small-winged, uncommon type.

Evo Monarchs

Plump, large-winged, rare type. Can dodge attacks.

Celestial Evos

Visually similar to Evos or Evo Larvae, dual-colored and glittering; the very rare type.

Collecting Evos

There are several sources of rare Celestial Evos available in Dungeon Boss depending on your Player Level and the level of your Heroes.

Dungeons (Evo farming)

Dungeons are a good place to find evos while you do events, open loot chests and collect Hero tokens. To obtain a specific evo, you can hunt in specific dungeons that have a chance of rewarding that evo. Evos appear as random opponents in dungeons. The possible Evo types that you can get are listed on the entry screen of the dungeon, while the frequency of appearance depends on the type. Celestial Evos are the rarest types and the most difficult to find. In addition, 8 of these Celestial evos are much rarer and even more difficult to obtain. A popular belief is that the chance of encountering a Celestial Evo is approximately 1%. The probability of success increases with number of passes. This means that if there is a 1% chance, then 100 dungeon runs have a 63% statistical chance of success. During the Evo Extravaganza special event, the appearance rate for celestial evos is increased by 5. A supposed probability of 3% chance for appearance will result in a 96% chance of success for 100 runs. It is best to take advantage of this and hunt for celestial evos during these events.

The downside of a focused hunt for an evo in dungeons is that the search is monotonous and it consumes a significant amount of stamina. However, in the event of a successful outcome, you will have exactly the evo(s) you are looking for. Quick loot can be used to hunt Evos.

Some Celestial evos are available only in the higher chapters of the Campaign so that a specific Player Level is required.

(The formula for the probability is: p=1-(1-c)n, where c is the supposed chance (probability) to face an Evo in range from 0 to 1. A value of 0.01 means 1%, and a value of 0.03 means 3%. n is the number of dungeon runs.)

Evo Island

Evo Island is open every week on the weekdays (Monday through Friday). Here you have the possibility to beat up to five dungeons every day (depending on your Player Level). Each dungeon run offers the chance to get an evo, including a rare Celestial evo. Because Celestial evos have two colors, they appear twice a week. For example, Shadow Evos are light (yellow) and dark (purple), and because Evo Island cycles through all 5 five elements throughout the week, it is possible to obtain Shadow Evos 2 out of the 5 days Evo Island is available every week.

The Evo island stages consume stamina in increments of 5. The first stage costs 0 stamina, the second costs 5, the third 10, etc.
