Roll a D6 at the beginning of each round of combat for every model participating in a combat in which the Basilisk is involved (including friendly models).
On the first turn of combat with the Basilisk a wound is inflicted on a result of a 6, on the second turn a wound is inflicted on a 5+, and so on to a maximum of 2+. Armour saves and regeneration may not be taken against the Basilisk’s vitriol, although other Ward saves and Magic Resistance may be used.
