Those heavy guys have bows and arrows and trebuchets! Do we get anything cool like that?
We get guns. Yep, guns. No, put down the
Colt .45. They're rubber band guns (RBGs). Sounds wimpy until you see
or are shot by one: we use stretched surgical tubing. Ouch.
The specific text from the most recent edition of the Middle Kingdom Rapier Marshall's Handbook is as follows:
2.2.4 RUBBER BAND GUNS (RBGS)
Only RBGs that are designed to fire surgical/medical rubber tubing loops as shot (ST-Shot) can be used.
The ST-Shot will not contain any metal. RBGs will mimic the appearance of period firearms. RBGs will
have a trigger mechanism to fire. There are no size restrictions on RBGs (e.g. swivel guns and cannons are
acceptable). There is no limit to the number of ST-shot a RBG can fire simultaneously. If the RBG is also
a rigid parry device, it must pass a rigid parry inspection.
Note the fifth and sixth sentences: those are the rules are where we
get the siege weapons from. They're up to our imagination, and Warder
Kevin O'Shaughnessy has quite a good one. See below under Resources for his piece on the subject.
As in the Heavy lists, you can't use 'em in tournaments. Only melees.
