The Mystic — 6 points
(Astropath/Warp-Seer/Sanctioned Psyker)
If a unit of Daemons, a Greater Daemon or a Deep Striking unit enters play within 4D6" of an Inquisitor with a Mystic Henchman (roll when each unit enters play), both he and the rest of the retinue may immediately take a 'free' shot at them. These shots are taken before the enemy unit moves, as an exception to the normal turn sequence, and the unit counts as stationary. Aside from this, the normal shooting rules apply. If the Inquisitor has two or more Mystics in his retinue, he may instead nominate one unit with a model within 12" of him to immediately take these 'free' shots at the enemy unit that has entered play.
Errata — Chapter Approved: Codex: Daemonhunters Q&A (v1.0): Yes, this triggers a free shot every single time a unit of Daemons, Greater Daemon, or Deep Striking unit enters play within range — there is no once-per-game or once-per-turn limit.
