Q-BRANCH (of the GURPS forum)

[Gumby Bush]

Here's one suitable to a low tech game:

Assassin's Stick:
Combination Weapon (1 at a time)
6' Snorkel
Spyglass
Blowpipe
Quarterstaff
Expensive & Disguised
$922.5 4.6lbs

There are two questions I had about whether this is totally RAW:
Combining a blowpipe and a quarterstaff is not explicitly supported, and you cannot ordinarily combine weapons with that rule. Applying Expensive to weapons is likewise not supposed to be allowed. I designed it for a fantasy game and assume it is made of essential wood.
