Just to verify... The permitted tables currently are these right:
Armor
Weapons
Adventuring gear
Containers
Tools
Mounts & other animals
Tack, Harness and drawn vehicles
Waterborne Vehicles
Trade goods

(just wondering if we should scratch the [s]warship[/s] rowboat or not...)

There's one thing we don't see on the lists that would be appropriate for Lauk...
Could we have some high-quality leather pieces (used for his spellbook)?
If so, how much gold to cut off? Trade Goods table (page 157) should probably be useful to estimate price.
