To setup the spear quiver I simply used a combination of soft position constraints and specific weighting. The spear basket was weighted 100% to the yellow implicit sphere, which was a soft position constraint of one of the spine bones. The top section of the spears were weight 100% to the green implicit, which was a soft position constraint of the yellow implicit. The spears' grip was weighted appropriately so that it stayed with the shaft. I also set up a couple more soft position constraints with the blue and red implicates and weighted appropriately to give the spears' feathers more life (red constrained to blue which was constrained to green).
This similar method was used for the dreamcatcher and antler sinew as well.
You've noticed that these soft constraints will interact real time. This is because its based on the previous frame for its calculations. If you happen to be rendering on multiple machines, you may need to bake in the animation of the constraints.
Do this in the animation toolbar by plotting all transformations for all the soft constrained objects.
After the transformation is baked in, you'll have to remove the constraints from everything to make sure it does overwrite the animation already baked in. This may take a while depending on the number of constraints you have setup.
The only other complicated feature of the rig on Moosah and Chub was the Syflex setup, which was created for the two reigns, flag and canopy cloth. Having the Syflex cloth react with the canopy branches and loops involved a huge combination of Syflex nails and position constraints, but Syflex is a whole other setup.
