提案/Suggestion
I personally think that training mode is one of the best additions to the game, but I believe that we should be able to inflict status effects on the sand bag to test the maximum capabilities of status inflicting weapons.
Moreover, the sand bag could have a setting that chooses the stats of a monster that you want to test on (not the actual monster but the corresponding stats attributed to it, such as overall health points, status effect resistance/weakness and elemental resistance/weakness).
It could also be added the option to invite people to do a group training, because I just think it would be very funny to have people just jumping a sand bag for no reason.
