Ogre-size kemari balls (despite being made from leather and some sticks forming its interior skeleton), according to "heavy objects" rules, have deadliness 12 (more than anything), because variable factor is size (silhouette.), instead of mass.

Please, fix it.

**** for a short moment I wondered who was this Kemari dude?

(just joking )

This topic is near and dear to my heart. In fact I would offer that the true measure of a samurai is their mastery of kemari.
