Synergy finder
Pick a keyword to see what generates it (hero abilities, ...) and what reacts to it (relics that trigger when it happens, ...). Combine both sides for a synergy.
How synergies are built
Synergies in this game come from pairing a generator with a reactor around a keyword. A hero who applies Poison every combat is just a damage source until you also hold a relic that does something extra to poisoned enemies. The reverse is equally dead: reactors do nothing without a source. Knowing which side you secured first tells you what to look for during the rest of the run.
There are no bonuses for fielding a number of a class
Unlike many auto-battlers, there is no system here where fielding three of the same class automatically grants a team-wide bonus. A class determines which primary stat scales that hero’s abilities. Individual abilities can still count classes — "for each Tank in combat" and similar — and those are listed with their real numbers on each hero page.
How this list is built
The keyword lists are built by going through every hero, specialization, item, relic and rank upgrade description and sorting them by the keywords they mention. Whether something generates or reacts to a keyword is decided from how the description is worded. When an update changes the text, the lists are rebuilt.
