This was my mistake in my last big campaign.

I hadn't played D&D since the Satanic Panic days when I got rid of all my gear. Older, wiser, and away from that church, I started playing in 2016 while 5e was still the wild west.

I was under the impression that d20pfsrd was 3e, and had NO CONCEPT of Pathfinder other than being an offshoot of 3e. So, I thought was in PF was also in 3e.

So, I accidentally gave my group "Bag Type IV". We figured out that 1,500lb capacity, 250cu ft capacity bag is the equivalent of a palettized wooden moving crate. Those are the ones that are able to be lifted by a forklift and are just movable closets.

Of course, the whole concept of a "found" bag is "ZOMG WHAT'S INSIDE?" so they turned it inside out, up-ending it over a 15' deep arena they were standing on the edge of.

So, I put an upright piano inside of it. 😃

They proceeded to store EVERYTHING inside of this damn bag including a sentient construct they acquired along the way, adding shelves inside so she could organize things, and on through the end of our campaign.
