Backpack Brawl Mycella is the quickest way to find the current requirements, rewards and practical steps without digging through several menus or announcements. Season 7: Undergrowth introduces the fungal hero on September 28, with a kit that grows a single Spore into different fungus lines and eventually larger colonies.
This page focuses on what you actually need to do in game. Where live rewards or event details can change, the wording below separates confirmed information from details that are still being reported differently.
How Backpack Brawl Mycella works

Mycella’s defining mechanic starts with a Spore. On shop visits, that Spore grows into a Fleshcap, Mindcap or Rotcap depending on the neighbouring items, and the fungus can continue developing into Clusters and Colonies.
That means placement is part of progression rather than only a combat optimisation. What sits beside the Spore can influence what it becomes, so rearranging the backpack before a shop transition can be as important as the next purchase.
Mycella Mindcaps and Insanity
Mindcaps interact with Star Pets and apply Insanity. Insanity drains the opponent’s maximum health and ignores Resist, giving Mycella a route that pressures the opponent differently from ordinary direct damage.
Because the fungal lines have different functions, do not treat every Spore as something that should grow into the same result. Build around the neighbours and effects you actually need.
How to unlock Mycella
At the start of Season 7, Mycella is exclusive to the Gold Pass. The official schedule then puts her into the Subscribers weekly rotation in week three and the free rotation in week four.
After week four she becomes available for general purchase with Gems and normal purchase options. Players who do not want the Gold Pass can therefore test or obtain her later in the season.
Season 7 Undergrowth details
Undergrowth lasts 50 days from its September 28 launch. To count for the season leaderboards, a hero must play and complete at least one run during the season.
For Mycella specifically, the useful learning curve is understanding growth timing. Watch what a Spore is adjacent to before each shop visit, then plan the next stage of the fungus line instead of filling every empty backpack square immediately.

Backpack Brawl Mycella practical checklist
Before you start, open the relevant in-game screen and compare it with the requirements above. Backpack Brawl Mycella is easiest to handle when you confirm the live objective, event or system first rather than relying on an old screenshot. That is particularly important around launch-day updates, when a server-side change can alter a reward or requirement without changing the basic route.
Work through one condition at a time if progress is not behaving as expected. Check the mode, starting lineup or item eligibility where relevant, then complete the activity and return to the menu that records progress. This makes it much easier to identify the condition that failed instead of changing several things at once.
For limited-time content, claim completed rewards as soon as they become available. For permanent systems, keep the page bookmarked for the route and troubleshooting details rather than rushing through a choice that cannot be reversed. Where the game offers a permanent branch, spend or role decision, the live confirmation screen should be the final check before committing.
The Click will keep Backpack Brawl Mycella on this URL when the same search intent changes. That avoids splitting useful updates across near-identical pages and gives returning players one place to check what is current.
