A Smoker may be played when another Personality card is played, or when an eruption effect is applied. The person playing the Smoker redirects the Personality card or eruption effect to another valid target.
The second target must meet all the conditions of the card or eruption effect, as decided when the first target was chosen. A Smoker may not change the full original effect it is redirecting. The entire effect is passed along, without modification
A Smoker may only be used to redirect Personality cards and eruption effects. It may not redirect anything else, including When Solved effects.
For example a Lurcher card is played to steal 2 of resources. The player does not want their resources to be stolen so a Smoker card is played to redirect the effect. The effect is redirected to a player who has the resources.
