Heavy Load
A little known fact is that the “half” in “halfling” doesn’t refer to humans but to ants. Think about it.
Currently weighing in at around 40-odd pounds, halflings (and gnomes) have no penalty to Strength or carrying capacity despite being a quarter of the mass as a human. With a 16 Strength a halfling can trudge around carrying 160 pounds and lift around 800 lbs. That’s twenty times their body weight. Assuming once could find a sturdy board that was light enough, a single halfling can lift twenty other halflings over its head.
Which means just one thing: halfling Cirque du Soleil is amazing.
I’m actually pretty sure they do have a weight lift penalty.
