Hi @xzxixin,

Thank you for reporting the bugs regarding the challenges “Symbiote Smackdown,” “Mystic Mayhem,” and “Boss Rush.”

For “Symbiote Smackdown,” you are correct; the Enraged Symbiote should trigger when attacked rather than when it attacks. We will address this in the next version.

For “Mystic Mayhem,” we believe this is how the challenge is designed, as it states:

Using the Adam Warlock Nemesis and the Doctor Strange Nemesis encounter sets as modular encounter sets.

For “Boss Rush,” we currently do not have plans to add this challenge due to a lack of rules, such as how to handle the “encounter sets” and “modular sets” for each scenario.

Thank you again for your feedback!
