Illimat: The Rusalka Rulebook

The Rusalka is a promotional Luminary card for Illimat (2018), an expansion for Illimat. It has no standalone rulebook; its rules text was published by the designer in the liner notes of "I'll Be Your Girl: Exploded Edition" (The Decemberists boxset) and is quoted below.

The Rusalka (Luminary)

When you play a card in to the field of The Rusalka, change the season of the field as if you had played a face card, regardless of the value of the card you played.

When you collect The Rusalka, take one card at random from the hand of each player and add it to your harvest pile. Opposing players wait until after their next play to draw up.

Source note: this is the complete published rules text of the card. Use it with the Illimat base rules.
