There are 9 Minion Effect tokens that trigger special effects. After all Minion tokens have been placed, resolve any Minion Effects that were placed, and then discard them. Try to resolve them in the order they were drawn. Refer to this list when you draw a Minion Effect:

All characters lose $1.

All characters reduce 1 skill of their choice by 1 on their skill track. A skill cannot be reduced below its minimum.

All characters must cover 1 icon on 1 card in their hand. (Use an Indicator token with its X side up.)

The covered icon cannot be used when that card is played.

If a card has an icon covered due to this token, it can still be discarded for a discard effect

All characters on a Location with 2 or more Minions lose 1 health.

Add 1 Minion token to all Locations that contain exactly 2 Minions. Effect tokens do NOT count as Minions.

All Minions that contain the color shown move to characters on connected Locations.

If a Minion could move to more than 1 Location to reach a character, the players choose which Location that Minion moves to.

Check the wraparound paths on the top, bottom, and sides of the board for connected Locations.

Minions further than 1 connection away from a character do not move.

Minions already on a Location with a character do not move to another character.

Minions on the same Location as the Villain do move toward a character.

Minions cannot enter Knuckles' Location.
