The World Born Dead
Ghost Touch Oil
This clear oil has a slight tint of gray, and
strange, wispy forms seem to swirl through it. When applied
to a weapon, ghost touch oil allows it to affect incorporeal
creatures normally for the next 1 minute.
Applying ghost touch oil to a weapon of any size is a full-round
action that provokes attacks of opportunity. One
flask of ghost touch oil contains enough liquid to coat one
weapon of Medium size or smaller. A Large weapon requires
two flasks, a Huge creature four flasks, a Gargantuan weapon
eight flasks, and a Colossal weapon sixteen flasks.
