Power of Hysh

Power of Hysh is a spell that has a casting value of 6. If successfully cast, until your
next hero phase, the Sunmetal Weapons ability for the caster and/or the unit they are part of causes mortal wounds on an unmodified hit roll of 5+ instead of 6. Any number of LUMINETH REALM-LORDS WIZARDS can attempt to cast Power of
Hysh in the same hero phase.
