Swooping across the battlefield comes the Sacred Familiar.
This model attachment can be taken once for each spellcaster deployed in
your Halodyne warband and offers several effects to boost your magical
capabilities including increasing your spellcaster's MAG skill. Not only
that, but the Familiar can also channel spells.
Although very squishy, the Sacred Familiar is exceedingly difficult to hit with its DEF of 14 (+2 against missiles).
If all else fails, the Familiar unleashes an explosive surprise when it dies!
