As posted by Kaylar on the Assassins bulletin board:
The number of weapons that can be used with inhume have increased.
For the ranged methods, any ranged weapon can be used and for the stabbing
method, any dagger that has stab attacks can be used. For the beheading
method, any sword (not heavy swords) that has slice attacks can be used,
note that this means that the short scimitar which could previously be
used to inhume now cannot.
While any weapon can be used for these methods you may still find that some
are better than others. So, while you may be able to inhume with a javelin
you may find that four feet of steel is not the most covert option.
The judge command will tell you whether a particular weapon can be used to
inhume.
Additionally, the throw command and fired weapons have changed and should
behave in a similar way to each other. Some crossbows now need skills or
time to load and the "load" command will need to be used rather than put.
Assess hasn't been changed yet.
While the changes to thrown inhumes will not affect Ninja unless you have advanced fi.ra.th, this is a great improvement to ranged combat. The changes that I've observed so far are: your fi.ranged skill (not the sub-skills mind you) plays a part in your defense against ranged attacks, and you have a chance of remaining in hiding after firing/throwing much like an inhume.
