When placing a Token on a Forest, the player has to sacrifice one of their three Tokens for that turn. The player does not have to sacrifice a Token, if any of the following is true:

a) The player has a Token on an adjacent Forest space (see below image),

b) The player has a Token on a Forest space that is adjacent to a temple which is itself beside the Forest space where the player is placing a Token (see below image),

c) The player is crossing a waterway, or

d) The player is using the ”Move a Token” guardian action to move their Token.

EXAMPLE: Blue player does not need to sacrifice a Token to place a Token into the marked forest spaces. Red player needs to sacrifice a Token, since he does not have a Token in a adjacent forest.
