Effect: This spell creates a broad, 
bowl-shaped dome of force over the caster's head, 10 feet in 
radius, shimmering violet in appearance. The dome will 
follow the caster wherever he or she travels. The dome will 
not only shield the caster from rain, sleet or snow, but also 
against physical or magical attacks from above, such as 
siege missiles, giant-hurled boulders, or a breath weapon 
from a flying dragon. The force umbrella provides a +4 
saving throw bonus against magical attacks from above, 
and a -6 AC bonus against physical attacks from 
above. The umbrella will also deflect 75% of arrow or bolt 
attacks from above or a high angle of indirect fire, such as a 
volley of arrows. It will conform to restricted spaces and 
allow the caster to move through narrow openings.

MC: A miniature umbrella made of wood and leather and a pinch of diamond dust.
