Morg Danforge:
I suspect something horrible's going to happen before we get another action each, but a question on pushing, pulling, and lifting (which is strength*30 pounds [so 540 for Morg]): is that the maximum, requiring a good roll vs some DC?
What happens if several characters (or some helping others for advantage [Morg may not need help, because the crowbar may already give him advantage]) do it at the same time? Is it all their strength*30 in pounds added together?
Thank goodness 5e simplifies it to make pushing, pulling, and lifting the same; because I sure can't lift what I can push, or push what I can pull.
All the push/pull/lift rules are generally to do with whether you are able to push/pull lift something at all, and if so how fast you can move while doing so. In this particular case, we'll handle most things do to with escaping the cages with a simple strength ability check (unless you're planning to drag a metal cage to the surface, for instance).
