A 10-point character
advantage in
GURPS Supers. It is intended to simulate the idea that
cats always land on their feet, so
catlike superheroes can be that way too. It's a fun ability to
play around with, and great for character
flavor, but unless you fall rather
frequently, those ten points may just be
wasted--just use a few points on Acrobatics
skill if it seems too
expensive.
From
GURPS Supers,
2nd edition:
"Character subtracts 5 yards from a fall automatically (this is considered an automatic Acrobatics success; don't check again for it). A successful DX roll halves all damage from a fall."
