Imaginarium Theatre Explained:

Imaginarium Theatre is a highly restrictive gamemode that pigeonholes the player into using characters of three elements, giving six "Principal Cast" characters (characters that every player must include in their "cast"). There will also be four "Special Guest Stars" selected every month, and you may use them if you have the character above a certain level. Finally, the "Alternate Cast" members are made up of characters you own that are above a certain level that you may use in the Theatre. For the highest difficulty (Lunar Mode), around 28 characters are required to complete it.

The theatre has ten rounds (at the highest difficulty), plus two special rounds where you can draw a Lunar Arcanum if both are completed. Between the 10 main rounds, four contain bosses (from the overworld or a local legend) that you must beat within a certain time.

For example, this month's three elements were Pyro, Hydro and Electro. The six Principal Cast characters are Mavuika, Clorinde, Sigewinne, Dahlia, Yanfei and Iansan. The four Special Guest Stars are Venti, Xianyun, Xilonen and Collei. The bosses were the Perpetual Mechanical Array, the Emperor of Fire and Iron, Knuckle Duckle, and Maguu Kenki.

This is a pretty good combination of elements as it opens the door to strong reactions such as Vaporize or Overload. However, players aren't super lucky every season. Especially if you lack strong DPSes for certain elements, or don't have enough built characters to clear, or the reactions available aren't strong.

**What would be in your opinion, the worst possible Imaginarium Theatre combination of Bosses and Elements? (can also add Principal Cast and Special Guest Stars)**

(this is definitely not a hoyo employee trying to make the playerbase miserable for the feb 2026 theatre)
