Extend Astromatrix

If successfully cast, pick 1 terrain feature wholly
within 18" of the caster and visible to them.
Any Damned, Arcane, Inspiring and Mystical
scenery rules for that terrain feature only apply
to SERAPHON units, while any Deadly and
Sinister scenery rules for that terrain feature do
not apply to SERAPHON units.
The caster slightly extends the range of the
Astromatrix so that it encompasses new lands.
