Rules does not say how the mentioned effects interact with actions caused by passive conditions.CRF, Turn Sequence, Organization Phase wrote:Effects that are played during the organization phase, and depend on the site or site
path of a moving company, create an effect which is not declared until the new site is
revealed. If the site or site path is not of the appropriate type when the effect resolves,
the resource has no effect. If the company has multiple movement/hazard phases on
the same turn, the card applies separately to each phase, having an effect only if the
correct conditions are met.
If for example a company on which Secret Passage has been played moves from Rivendell to Zarak Dûm; Scorba Ahunt and Snowstorm are in play; a timing is uncertain.
There are three actions/effects that compete for be first declared at beginning of M/H phase:
Effect of Secret Passage, attack from Scorba Ahunt, returning effect of Snowstorm.
"For purpose of timing an effects played during the organization phase that depend on the site or site path of a moving company are treated as action caused by passive condition."
EDIT: Corrected ridiculous title of thread.
