SCULPT SPELL [METAMAGIC]
You can alter the area of your spells.
Prerequisite: Any metamagic feat.
Benefi t: You can modify an area spell by changing the
area’s shape to either a cylinder (10-foot radius, 30 feet high), a
40-foot cone, four 10-foot cubes, a ball (20-foot-radius spread),
or a 120-foot line. The sculpted spell works normally in all
respects except for its shape. For example, a lightning bolt
whose area is changed to a ball deals the same amount of
damage, but affects a 20-foot-radius spread.
A sculpted spell uses a spell slot one level higher than the
spell’s actual level.
