[pnpgm] Keg assist casting

[Alex Koponen]

While having some seamanship skill Z'leyra knows her skill is not the 
equal of a full storm like we are headed into. She hunts down an empty 
or nearly empty cask and some rope and in her cabin sets to work rigging 
a harness so that the cask will give her flotation if she should end up 
in the water. As she does this she ponders the possible need for magic 
to save the ship, crew and passengers and the possible ways it could be 
done.

Not having Sea Powers she doesn't have the Calm Sea spell that she has 
heard of. She wonders if any in the party know the spell. Staff in one 
hand, cask in the other she will make her way around asking those she 
knows can cast magic if they know the spell. If so, she will offer her 
assistance in the form of high EL Purification and Luck spells and 
possibly the loan of her staff to improve the odds of successfully 
casting the Calm Sea spell.
