5. Psychic Stimulus

Select a friendly GENESTEALER CULTS unit within 18" of the psyker. Until the start of your next Psychic phase, that unit can charge even if it Advanced (though not if it Fell Back) and they always fight first in the Fight phase, even if they didn't charge. If your opponent has units that charged, or that have a similar ability, then alternate choosing units to fight with, starting with the player whose turn is taking place.
