Prayer of Grimnir's Fury

At the start of your hero phase, 1 friendly model
that knows this prayer can chant it. If they do
so, make a prayer roll by rolling a dice. On a
1-2, the prayer is not answered. On a 3+ the
prayer is answered. If this prayer is answered,
pick a friendly HERO that is not mounted on a
MAGMADROTH and is within 3" of an enemy
unit and within 12" of this PRIEST. Make a pile
in move with that HERO, and then attack with
all the melee weapons that HERO is armed with.
