Universal Rule.
When a Magister riding the Doom Bell chooses targets for spells with Type Direct, it ignores the restriction of only choosing targets in its Front Arc.
When a Magister riding the Doom Bell chooses targets for spells with Type Missile, it can draw Line of Sight at 360° and from any point of the Doom Bell's base, and may cast Missile spells even when Engaged in Combat. All non-Bound Spells cast by the Magister gain +3" Range.
